This gives white a unique ramp option beyond the catch-up ramp, and Im excited to put it into a ton of decks
First, it's a three cost, with an ETB ability so you can drop it on the third turn
9 Jalira, Master Polymorphist Not Your Average Sea Creature Commander Jaliras puts a unique spin on this strategy and masks your true intent at least until the first Kraken of Serpent hits the battlefield
Whenever a creature dealt damage by this creature this turn dies, put a +1/+1 counter on this creature
With max speed, all your creatures have first strike, which is wonderful by itself, but it becomes stellar with the pump from this creature
It does very little against planeswalker-heavy superfriends decks and most combo and control decks
