Champions

Well, Ryze builds mana to boost his spells, generally picking up a moderate amount of tankiness along the way. Add a snare, aoe spellvamp on a fairly low cooldown and no skillshots and boom, easy caster. Damage isn't insane or anything, but not bad.

Yi is an autoattack champ with an amazing ult that makes him immune to slows and move and attack faster for a good long time(good for chase or escapes, or even just killing towers) one of the more annoying and effective harasses in the game imho, and a selfheal that helps lane sustain a good bit as long as your mana holds, and a free chunk of AD that can be boosted further on activate, also amazing at nuking towers. Very versatile. I won't go into AP Yi, but there's also that.

Malphite I picked mostly because he's the only true tank on that list. However, he's also relatively easy to get used to. Has a Q that harasses decently and also slows, some aoe attack speed debuff that tbh I never really use, a decent damage steroid that also helps a bit for farming, and an ult that make me lol every time it works correctly. Not my favorite tank by any means, but fairly simple.

Edit:I suppose I should amend the part where I said Yi was easy. He's a good learning champ.
