AltergeistLegend Anthology - Academy from
Notes & Combos
A very strong and affordable option for this event. The only UR that you absolutely need is Multifaker.
I would also consider One for One if you have it, but other than that I'm satisfied with the list.
Only ED monsters that are truly relevant are Hexstia, Artemis, and Linkuriboh. Nothing else comes up enough for it to matter much.
