Champion Yoshi, Egg Warior

When Champion Yoshi deals combat damage to a player, you may exile a non-land permanent they control with an egg counter on it. That player
creates a 0/1 Egg token with defender. You may
cast cards with egg counters on them as though
they had flash and may spend mana as though it
were any color to do so.
{2}{g}, {t}: Exile a card on the stack with an egg
counter on it.
Trample, Vigilance
