The 3 combo pieces

What must be in place

You have a card in hand with kicker or multikicker.

How to execute it

  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. With the Phyrexian Devourer triggers on the stack, cast Bioshift by paying {G/U}, moving all +1/+1 counters from Phyrexian Devourer onto Hallar.
  5. Resolve all Phyrexian Devourer triggers from step 2, causing you to sacrifice it.
  6. Cast any kicker or multikicker spell with kicker by paying its mana cost plus its kicker cost.
  7. 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.
