Without context it's hard to answer. They're both great champs. What area of the game are you working on right now?

Short answer is Scyl for general content, Trunda for arena. 

Long answer is we need to see your roster, where you are in the game and content to make an informed suggestion.

I'm Level 58 I have 8 Legendary's I just recently got Trunda then reached 180 days and unlocked Scyl. I I am struggling to stay in Silver Level 3 and 4 in Classic Arena and in Tag team I have never been past Level 1 BRONZE lol. I would love to go further in Doom Tower than level 40 and start doing some damage to Hydra. As far as my Roster do you want a screen shot?

Screenshot would be extremely helpful. :)

Sorry I just saw you can select this option LOL

This is all of my champions but I can share you what I have in my vault as well?

I'll just rock paper sizzers it LOL

I'd be curious to see what's in the vault given you have the key elements (Maneater/Pain Keeper) to a budget unkillable clan boss team and the makings of a high level Spider team (Mordecai/Achak/Coldheart, ideally wants Renegade and another Coldheart)

If you really prefer to choose between Scyl/Trunda, I think I'd like Scyl for overall content/gear farming. 

However, what is your dungeon situation like? You have the core for a 2 key UNM clan boss team, but that's going to involve taking a few champs up to 60, including Maneater, Pain Keeper and Fayne, to go with Ninja. I'm not sure about the 5th there since I can't spot an easy void stun target. I could see Corpse Collector being your affinity swap, too. That route will take more time, but getting NM/UNM going will help you progress in Doom Tower, Hydra and pretty much everywhere else long term by virtue of the resources higher level clan boss can give you. 

In general, we need to focus on making more 6*s vs 5*s. That will go a long way towards giving you effective teams. We can use quite a few of those rares - especially farmable ones - to expedite the process getting all the 60s you're going to need. 

All that said, a lot will depend on where you are gear wise, what you're able to farm consistently, etc. This page https://www.deadwoodjedi.com/speed-tunes-4/New-Budget-Maneater---3-Bosses-only-1-Comp will give you an idea of what the speeds will look like in a team like this, and if the stats are too much for you at the moment I'm fine with focusing on dungeons - specificially dragon - while you work towards that team. 

I realize that was a bit more than you were asking for, but you have the set up for a really strong account and wanted to give you all the options I could realistically see. Good luck. :)

Sure thing and thank you for your AMAZING advise I really appreciate it. Let me get some screen shots of my VAULT champions.

so I think i'd lean Bulwark as the stun target, with what I'm seeing.

That said, where are you in dungeons? I'm not sure if you got a chance to take a look at the link I sent you, but the speeds are very important (240-241 for Maneater, 218-222 for Pain Keeper). Ideally we'd be able to make convenient gear swaps for our stun target when switching between UNM/NM. 

you don't really need another at level 60, if you do it will be for some event what you need first is a good dungeon farming gear i would start with dragon 20, then spider, and finally FK, in that order, when you understand that, the rest comes easy. It is impossible to advance with a hero that has so little speed, you should think that having 2 turns before the enemy is 100% more effective over all, really only if you have a good hero who is a nuker and you have less than 200 speed. because you have +6k attack +280%cd

What??

60ing champs is ALWAYS something to be doing. Are you hitting Dragon 25 for under 1:30? Spider 25 for under 45 seconds? UNM Clan Boss for AT LEAST 2 key, while 1 key NM and Brutal? Beaten Hard Doom Tower on all rotations? If not, then you should be 60ing champs as a major part of the game.

Now OP, @ohadmeir79, it looks to me like you've got a Deacon, Ninja and Zavia 60'd. Sycl is a great next step in having a full team to run the level 20+ dungeons. She gets into a ton of teams even for the biggest whales because she brings CC, speed for your team, team healing, and revives. Amazing support champ.

Then I would consider both Mordecai and Achak to be a one-two combo against Spider, and can carry you through Spider 25. They run excellent as a pair, and bring AoE HP burn, AoE Freeze, TM decrease for the enemy and TM boost for you... skills which DESTROY Spider but also work everywhere else. I think they are your next two 60s after Scyl.

After those, and you can start farming Dragon 20+ and Spider to enhance your gear quality, you're ready to build that Maneater team that @dthorne04 mentioned.  Hopefully you will pull a SECOND unkillable champ rather than have to deal with Budget Unkillable. That team is requires gear or champ swaps from UNM to NM to Brutal, as well as champ swaps for different affinities. So, while it is a great team to run to get those Clan Boss rewards, the initial setup of such a team is an endeavour, especially for someone who is looking into making their 4th Rank 6 champ right now.

So to set your account up to farm the dungeons, then some of the beginning Arena stuff, I'd go:

1. Scyl  
2. Mordecai  
3. Achak  
4. Trunda (finally XD XD) 
5. Maneater and Painkeeper, your UNM/NM Clan Boss champs

And of course, if you get to any of these things and get stuck, just start a new thread and @ me. "Help me build the Mordecai/Achak Spider team" or "Help with that Budget Unkillable Clan Boss Comp"

You've got a great account, with great champs, and with some 60s and farming you'll be hitting all the late game content pretty quick. :D :D

This isn't the best example - and is pretty much cherry picking - for a few reasons:

Neither Mordecai nor Renegade need to be 60 for this specific team to function properly. 

I wouldn't advise a second Coldheart to be at 50 for almost anyone (also because you're likely going to use her in other places where you probably want her at 60), but you likely have great gear - and possibly great hall - which gives you a very different view of how to approach team building. 

You're at a very different portion of the game where you can overcome underleveled champions due to the aforementioned reasons, whereas suggesting to that to OP is likely putting the cart before the horse. Almost every single person playing needs to focus on teams of 60s, then getting the gear necessary to do things like this.

Following the plan @harleQuinn listed with regards to making these kinds of decisions relative to where you are in overall content will make the most sense for almost every player. 

Thank you @dthorne04 and @harleQuinn for all your help sorry to respond so late was taking a break for a few days LOL. You know how this Game can make you play for days AND hours. Now I am going to do my best to get those Champions to Level 60 you guys advised. Also I did just pull another Shadowkin Legendary Karato Foxhunter a couple of days ago.
