Charizard and Pikachu sit on my nightstand inconspicuously until I feel like fighting alongside or against figure players. After recently dumping Pikachu as a main/secondary because of just how bad I am with him, Charizard is the only amiibo I'll likely keep. I got incredibly lucky with Charizard, how he recently became available again at select stores and got him for 12 bucks, I almost dropped 30 on him on amazon and the order didn't go through, so I didn't bother to try again.
I'd have Robin too but I can't find him anywhere that isn't 40 bucks on amazon. It's sad the FE amiibos are so rare because they get more use out of any game more than any other amiibo, not to mention being able to play as/fight with/interact with them in Code Name STEAM and Fire Emblem Fates, meaning you can actually bring the blighters to life outside of Smash.
Hence why I really want Robin, probably the only other Amiibo that's not Charizard I will actually go out of my way to get.
