Sliver Queen + Phyrexian Altar + Illusionist's Bracers

Sliver Queen

Phyrexian Altar

Illusionist's Bracers

How it works

1. Activate Sliver Queen by paying 2.
2. Illusionist's Bracers triggers, copying Sliver Queen's ability.
3. Resolve both Sliver Queen abilities, creating two 1/1 Sliver creature tokens.
4. Activate Phyrexian Altar twice by sacrificing both Slivers, adding 2.
5. Repeat.

This classic engine achieves infinite creation and sacrifice by turning Sliver Queen into a token-producing powerhouse with the help of Illusionist's Bracers. Because the Queen's ability requires {2} to activate but isn't a mana ability itself, equipping her lets the Bracers double every activation into two token offspring for the price of one. Those resulting Sliver tokens are then fed directly into Phyrexian Altar, where sacrificing them generates the exact mana needed to pay for the next activation and keep the loop running indefinitely.
