Serpent of the Pass

Haste Whenever another Ally you control enters, put a +1/+1 counter on that creature and it gains haste until end of turn.

When this enchantment enters, create a Clue token. (It's an artifact with "2, Sacrifice this token: Draw a card.") Creatures you control with flying get +1/+1.

Choose one — • Destroy target creature with no counters on it. • Remove up to three counters from target creature.

Search your library for up to four land cards with different names and reveal them. An opponent chooses two of those cards. Put the chosen cards into your graveyard and the rest onto the battlefield tapped, then shuffle.

Deathtouch Whenever you sacrifice another permanent, put a +1/+1 counter on this creature.

(T: Add R.)

When this enchantment enters, create a 2/2 red Soldier creature token with firebending 1. Whenever a creature you control attacking causes a triggered ability of that creature to trigger, put a quest counter on this enchantment. Then if it has four or more quest counters on it, you may copy that ability. You may choose new targets for the copy.

Combustion Technique deals damage equal to 2 plus the number of Lesson cards in your graveyard to target creature. If that creature would die this turn, exile it instead.
