It is also most likely Syrus because Konami would consider him a "safe" character to release in terms of cards that won't be too powerful. So they are probably gonna get right on that as opposed to fudging around with multiple roaming events like with Espa Roba.
I use submarineroids and inverse universe from his event. And I'll say yes to his defense killers like drillroid and shieldcrush. Plus, can't wait for some duel dialogue between him and Zane. Syrus can be useful, I just get the feeling that Konami underrates him.
