Smolder vs Twitch

Last-hit minions with Super Scorcher Breath (Q): each kill with the spell gives you a Dragon Practice (passive) stack, which empowers your basic spells.

Poke with Achooo! (W): the sneeze slows, explodes on champions hit, and each champion hit gives you a Dragon Practice stack.

Build enough stacks for the final tier of Super Scorcher Breath (Q): it burns its target, and kills a champion who drops below a health threshold.

Escape or reposition with Flap, Flap, Flap (E): you fly over obstacles, bombarding the enemy with the lowest health.

Cast MMOOOMMMM! (R) to finish or slow from far away: the center of the breath hits harder and slows, and if it hits you, your mom heals you.

Get out of the Venom Cask (W) cloud fast: it slows you and adds a Deadly Venom stack every second, which powers up his Contaminate (E).

Ward your brushes and place a Control Ward on his paths: it reveals camouflaged enemies, and Ambush (Q) lets him reach you unseen.

As soon as he comes out of the Ambush (Q) camouflage, focus him with your allies: he's fragile and has no dash to escape.

During Spray and Pray (R), get out of his extended range until the effect ends: his bolts pierce every enemy, so hiding behind an ally won't protect you.
