The 4 combo pieces

• Crystalline Crawler
• Gideon's Sacrifice
• Pyrohemia
• Vigor

How to execute it

1. Cast Gideon's Sacrifice by paying {W}, causing all damage that would be dealt this turn to you or to permanents you control to be dealt to Crystalline Crawler instead.
2. Activate Pyrohemia by paying {R}, dealing 1 damage to each creature and each player.
3. Gideon's Sacrifice redirects damage to Crawler, which results in at least three +1/+1 counters being placed on it instead due to Vigor.
4. Activate Crystalline Crawler's first activated ability at least once by removing a +1/+1 counter from it, adding at least {R}.
5. Repeat from step 2.
