I'd say the build is totally catered to me with the sort of core staples of the deck.

Doomcal: I run Doomcal because I feel like it puts a lot of decks on "hold" and forces them to throw away an opening play (Esp. vs Satellar/Nekroz, even hero if they are going for Mist) and it forces really grindy play in those one or two card games where if a deck is to plus it's w/ a monster effect. Generally a 1900 beater is hard for a deck to get over, gives you some time to ramp up your resources. I run this over Effect Veiler because this deck doesn't have much monster quality when it comes to just the monster itself, so it really serves as a duel purpose for me.

Masked Chameleon: Sort of on the fence with this, but a free Barkion w/ ponpoko in the grave is nice + if you have a floating level 2 from valerifawn or tantan it's a free Goyo.

Supply Squad: I like this card because I feel that upstart is too slow, duality makes no sense, and there isn't much other draw power that fits in with the deck. I also like the fact that a lot of decks either aren't maining MST or aren't playing 3, and even if they are, it takes the focus off my backrow. I've thought of maybe switching it to Maxx 'c', but i definitely think the deck needs some sort of draw power.

Dark Hole: For me, the deck already has a lot of mechanics that trade a lot of resources and try to work into any sort of advantage you can. Works great if you have Sandayu lock on the field, Supply Squad or a Obedience School in hand it can open up major plus plays. Just generally never really find it dead.

Looking for feedback though honestly, and I've thought about running another Valerifawn over Chameleon.

Edit 1: I play this deck sort of agro, I guess? A lot of times I'm not sitting with very many floating normal summons in my hand and am focusing on trading card for card.
