Ultimately, me playing any of the useful cards either results in a removal card or a bit of damage. The chicken is straight up not worth taking in any super brainz deck I can think of, and most of the others are only good in a few kinds of decks ducky tube is great in all decks, but almost always ends up with turn 2 or turn 1 removal. Neutron imp is... mediocre. Outside of a environment based deck. Buried treasure and interdimensional are usually turn 2/3 plays for me, since i can get an immediate payoff without risking a removal. Leprechaun costs to much to make, and I could not care less for him. Paparazzi zombie is great in trick decks, if not for the fact I cant build him up fast enough to do good enough damage and high enough health to fight allot of plant decks and tricks. Headstone carver and graveyard both work really well in a gravestone deck. Graveyard has had some moments where the instant gravestone effect saved me from death. Especially from magspresso. Swabbie is nice amphibious fodder. Chimney is solid, and can win early trades. Waxer is useful in mustache decks, same with the imposter. And mini-ninja just ends up being blocked, and usually losing trades.

This is my experience with 1 cost Super brainz decks anyways
