don()shinobi, I'm actually not all that fond of Archetypes that rely on XYZ monsters for being their key cards. I mean, they're nice and all, but their effects are decidedly limited, and just one BTH/Sakuretsu/D-Prison or whatever can ruin a lot of hard work.
I usually prefer archetypes who have potent effects BEFORE you get to the XYZ/Synchro power-hitters. And, as far as I can tell from the anime's performance, OOParts doesn't look like it can do that, at least not very well.
It might be because I'm used to Synchros and such, or that there's little good XYZ support right now, but eh. The only XYZ I'd really like to use is Dragon Cannon.
