Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Akroma's Memorial

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Akroma's Memorial

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Phyrexian Altar by sacrificing Jegantha.
3. Activate Horde of Notions by paying , causing you to cast Jegantha from your graveyard without paying its mana cost.
4. Repeat.

This ingenious loop turns Jegantha, the Wellspring into a self-sustaining mana and sacrifice engine by leveraging its unique color restriction instead of fighting it. Because Jegantha's tap ability produces exactly one of each color, that mana easily funds Horde of Notions' active ability, which ignores mana costs to pull Jegantha right back out of the graveyard. Phyrexian Altar acts as the necessary exit strategy and recycling plant, sacrificing Jegantha to generate the exact colored mana needed to pay Horde of Notions again while feeding death and sacrifice triggers. Meanwhile, Akroma's Memorial sits on the battlefield quietly granting your entire team keywords like vigilance, trample, and haste, transforming this mechanical recursion into an overwhelming, keyword-soup board state.
