Kasakaer, Samurai Student

Whenever you cast an instant during your
main phase draw a card.
Whenever you draw a card you gain 2 life
and may tap target creature, its controller skips
their next untap step.
Kasakaer swung his katana through the air resulting
in a clean cut through a training dummy. Perfectly.
But not in his sensei's eyes. "Again!" Kusunoki yelled. He didn't know it yet but he was doing him a favor.
