Pretty much an Elite scarab for
, the only things that are different, is that you can only have 6 of these on field, and it has more attack upgraded, i'd say this is quite underpowered and basic.
here are 2 suggestion:s
keep this ability but add:
spread: sacrifice this creature to inflict poison on all creatures. accumulative.
or
replace the stats with 3/3 and
replace the ability with this: If this creature dies, all creatures become poisoned. accumulative.
so after sacrificing the first one, you can add an extra poison damage to all the previously affected creatures so they die faster.
this idea is probably OP for bone yard, wall and scavenger (putting it in play after poison inflicted), but i can't think of anything else that goes with the concept of pollution atm
