Improvised Arsenal + Mana Echoes + Signpost Scarecrow + Chishiro, the Shattered Blade

Improvised Arsenal

Mana Echoes

Signpost Scarecrow

Chishiro, the Shattered Blade

How it works

1. Activate Improvised Arsenal by paying 4, creating a token copy of it.
2. Chishiro triggers, creating a creature token.
3. When the creature token enters, Mana Echoes triggers, adding C for each creature you control that shares a creature type with the creature token.
4. If needed, activate Signpost Scarecrow by paying 2, adding .
5. Repeat.

This loop sets up an incredible factory of multiplying artifacts and spirits, fueled entirely by the synergy between Chishiro, the Shattered Blade and Improvised Arsenal. Every time you pay to copy the Arsenal, Chishiro steps in to spawn a Spirit token, which in turn triggers Mana Echoes to generate massive amounts of colorless mana based on your growing army of shared creature types. Signpost Scarecrow is right there to help color your mana as needed, ensuring you can keep churning out infinite artifact copies and creature tokens. As a glorious bonus, Improvised Arsenal's massive static buff—combined with Chishiro's end step triggers and the sheer number of modifiers—leaves your entire board infinitely powerful.
