Ghostly Flicker + Palinchron + Mnemonic Wall

Ghostly Flicker

Palinchron

Mnemonic Wall

How it works

1. Activate up to seven lands by tapping them, adding at least 2.
2. Cast Ghostly Flicker by paying 2, blinking Mnemonic Wall and Palinchron.
3. When Mnemonic Wall and Palinchron enter the battlefield, their abilities trigger.
4. Resolve the Mnemonic Wall trigger, returning Ghostly Flicker to your hand from your graveyard.
5. Resolve the Palinchron trigger, untapping up to seven lands.
6. Repeat.
7. If you control seven lands that can tap to produce at least 3, this combo nets infinite mana, and you may blink any other permanent besides Palinchron.

This classic engine achieves infinite mana and boundless enter-the-battlefield triggers by exploiting Palinchron and Mnemonic Wall as a self-sustaining loop fueled by Ghostly Flicker. As Palinchron enters the battlefield, its triggered ability untaps your lands to replenish your mana supply, while Mnemonic Wall ensures you never run out of gas by immediately returning the very same Ghostly Flicker from your graveyard back to your hand. Because Ghostly Flicker allows you to continuously blink both creatures simultaneously, you reset their powerful entry triggers over and over again, leaving you with infinite mana and any other associated triggers you desire.
