So, this afternoon I was looking at my cards and I thought 'wouldn't it be cool to make a deck for all my random vmaxes and vstars'. So I started with Flapple VMAX. It's pretty strong, with an attack that does 250 damage (but less the more damage it has taken) and a chonky-ish 320 HP. It actually synergizes really well with Arceus VSTAR, since they both use DTE. Flapple V is pretty cool as well, mainly the first attack that makes their next attack cost 2 more. Assuming they don't switch out (pretty unlikely now I think about it), it can make them attach a double turbo, which is 20 less damage to you, which is 20 more damage to them with the VMAX. This deck is kinda awful, but kinda goofy at the same time.
Slap with the flap apple :)
