There are many great multi-color combos, PPA is one of them: It checks a lot of the boxes of “great spec combo”:
- Has a lot of haste to make a move right when you need to (Zane especially allows for on-demand patrol zone shenanigans independent of card draw)
- Has a way to answer maxed heroes in Origin Story
- Has two of the best tech 3s in the game in Gunship and Archon, so it isn’t outclassed late game
- Boot Camp + Mox has ridiculous synergy that allows for fast cycling and constant offense
- Has the Peace tech 2 plan of Garrison and Drill Sargeant, which snowballs very quickly
- Has Battle suits and the peace tech line of almost exclusively “soldier” type units & “mystic” units in seer & Calypso Vystari
- Has a great early pressure hero in Onimaru
- Prynn maxband can answer some good tech 3 units
Etc. Purple Starter + Peace + X is strong in a lot of combinations
