Hi, I'm new to the game and I'm pretty sure I'm wasting loads of time, lol, so I thought I would ask a couple questions and see what kind of tips I can get, if y'all don't mind.

1. Where do I find out how rare my champion is? I saw a screen shot on here that showed it, but I can't find it in the game.

2. Does anyone have tips about which champions are best to keep and which are good to use to rank up other champions? I have a feeling I'm sacrificing champions that I shouldn't be. I've been going by their reviews, since I figured it's better to have ones that perform well in all the different places to fight. Is this wrong?

3. One last one (for now lol). I'm beyond confused as to which artifacts to put on each champion. Any simple tips? I'll be honest and say upfront that I'm not going to spend an hour every time I equip a champion,  but I would like to know if there's a simple way of doing it? I get the rankings and rarity and even the basic equipping with the first few types like life, attack, defense, etc...it's just when I get into the ones where the sets are in fours.
