Jegantha, the Wellspring + Horde of Notions + Viscera Seer + Frostcliff Siege

Jegantha, the Wellspring

Horde of Notions

Viscera Seer

Frostcliff Siege

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Viscera Seer 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 relies on turning Jegantha, the Wellspring into a self-recycling engine, tapping it for its colorful five-mana output to pay the activation cost of Horde of Notions. Because Horde of Notions lets you play an Elemental from your graveyard for free, Jegantha—which conveniently happens to be an Elemental—bounces right back onto the battlefield to do it all again. Viscera Seer acts as the sacrificial outlet to close the loop, granting you a free sacrifice mechanic that triggers infinite scrys while feeding the graveyard for the next iteration. Meanwhile, Frostcliff Siege quietly supports the battlefield by providing your creatures with an aggressive stat boost, trample, and haste under its Temur mode, ensuring your engine runs with maximum efficiency.
