Hallar, the Firefletcher + Phyrexian Devourer + The Ozolith

Hallar, the Firefletcher

Phyrexian Devourer

The Ozolith

How it works

1. Activate Phyrexian Devourer by paying 0, exling the top card of your library and putting a number of +1/+1 counters on Phyrexian Devourer equal to that card's mana value.
2. If Phyrexian Devourer's power becomes seven or greater this way, it triggers.
3. Holding priority, repeat from step 1 until you have an empty library.
4. Resolve the first Phyrexian Devourer trigger, causing you to sacrifice it.
5. When Phyrexian Devourer leaves the battlefield, The Ozolith triggers, putting a number of +1/+1 counters onto itself equal to the number Phyrexian Devourer had.
6. At the beginning of combat, The Ozolith triggers, moving its counters from itself to Hallar.
7. Cast any kicker or multikicker spell with kicker by paying its mana cost plus its kicker cost.
8. Hallar triggers, putting a +1/+1 counter on itself, then dealing damage equal to the number of +1/+1 counters on it to each opponent.
