Whenever you cast an instant or sorcery spell, Clever Infiltrator gets +2/+0 until end of turn and can't be blocked this turn.

Until end of turn, if a source you don't control would deal damage to you or cause you to lose life, mill that many cards instead.

• Town Justice deals damage to target creature or planeswalker equal to the number of Citizens and/or Peasants you control.

Whenever a card is put into a graveyard this turn, you may put it on the bottom of its owner's library.

When Spellblade enters, you may exile an instant card with mana value 2 or less from your hand.
