What?

I've seen Lucina Emblem, Chrom Emblem, Ike Emblem (& Soren), and I've seen a video where someone fought literally 4 Lilinas (none of them were LA!Lilina btw)

Never seen a Zelgius emblem but I did once stumble upon a Takumi emblem

I onced fought against a team with 3 Fallen Takumi and one regular Takumi. 3x Skadi effect almost destroyed the shit out of me lol.
Btw someone posted here before showing 4 +10M!Grima with all optimised skill sets. We just need to remember there are whales everywhere, and we should be grateful because technically they sponsored this game for F2P players :)

I've stumbled upon a roy emblem before

I've seen one with three BKs and a Zelgius, but I'm working on Legion emblem at the moment since it works thematically.

I've got a team with 3 Lyns and LA Hector. They're all different variants of Lyn though. This Zelgius thing is outrageous (and probably doesn't perform overly well).
