Hmm, 8 seems like too easy a requirement. Maybe bump it up to 10? Venomonarch is also really really good, probably want to tone it down.

Venomirror is a cool card.

when successfully inflicting battle damage while conversing into building up counters have to be regarded differently. they have to attack more frequently than monsters that inflict actual damage can go for less number of attacks like 3-4 successful attacks as the lowest but not to mention that a couple of cards will delay the current goal for other priorities. I can stimulate for 10 but know that they cannot inflict battle damage which is their major drawback.
