Alela, Artful Provocateur + Shimmering Wings + Phyrexian Altar + Kaya, Geist Hunter

Alela, Artful Provocateur

Shimmering Wings

Phyrexian Altar

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Cast Shimmering Wings by paying , targeting any creature you control.
3. Alela triggers, creating two 1/1 Faerie creature tokens with flying.
4. Activate Phyrexian Altar twice by sacrificing both Faerie tokens, adding .
5. Activate Shimmering Wings by paying , returning it from the battlefield to your hand.
6. Repeat from step 2.

This delightful loop turns a simple enchantment into an infinite engine by exploiting Kaya, Geist Hunter's token-doubling static effect. When you cast Shimmering Wings, Alela, Artful Provocateur sees the enchantment and triggers, but Kaya's active -2 ability doubles the payout into two Faerie tokens instead of one. Those tokens are immediately fed to the Phyrexian Altar to generate the mana needed to bounce Shimmering Wings right back to your hand with its own activation cost, leaving you flush with infinite sacrifice and enter-the-battlefield triggers.
