User blog comment:IcyDevil34/Next Key LRIGs?/@comment-35126423-20180920070419/@comment-29727671-20190421105248

Nanashi with a bazooka is what I wanted to see. LOL!!!

We are going to have 3 different Devil decks, huh. Well, their play style is different enough, hope they do something interesting with Tawil, I like the Red-Devil combo, compared to her original White-Angel.

I think the youtuber thing will have 3 different LRIGs of the same LRIG type being compatible with each other, so you could combine them however you want to create unique decks. The spell thing is probably tied to the LRIGs, some effects giving them counters and with each counter new effects unlock (kinda like "choose 1 of these" effects, but stronger being all of them simultaneously?). Different colors would have them focus on different mechanics.
