Evolve a Pokemon Card : If you have an Evolution Card for a Pokemon thats in play, you can place it on top of that Pokemon to evolve it
It just has such a convenient split of damage for such a low low cost
It also grants you protection from everything until your next turn when it enters the battlefield, which makes it a good target for blink effects that can trigger that multiple times
These tasks can include things like winning a particular trick, winning different tricks in a certain order, or even making sure another player never wins a trick
As someone who used to run it, I can confirm that if this card were to hit the battlefield, youd win the game that turn
