The White Tiger

Companion — Each permanent card in your starting deck has an activated ability. (If this card is your chosen companion, you may put it into your
hand from outside the game for 3 as a sorcery.)

Abilities you activate that aren’t mana abilities cost
{2} less to activate. This effect can’t reduce the mana in that cost to less than one mana.

{1}, {t}: Target creature can’t block this turn.
