I play some Standard and Modern, but mostly I draft.
My Puca points go towards improving my Commander decks. I have a deck for each three-color combination:
Sharuum, The Hegemon - Artifacts
Kess, Dissedent Mage - Doomsday Combo
Karrthus, Tyrant of Jund - Big Dragons
Gahiji, Honored One - Tokens
Roon of the Hidden Realm - Blink effects
Ruhan of the Fomori - You did this to yourself
The Mimeoplasm - Mill/Graveyard stuff
Kaalia of the Vast - Aggro Angels/Demons/Dragons
Riku of Two Reflections - ETB effects
Karador, Ghost Chieftain - Reanimator
