I took a bit of a gamble on this low mana 'monsters lose all abilities' battle - by playing just one monster with the Kitty...
I thought a high health monster combined with summoner's heal might just help him hold out long enough to kill sufficient monsters quickly enough so that there wasn't sufficient damage left to counter the amount of healing, and it worked out pretty much perfectly....
So beginning of R6 there's a heal, then flesh golem goes next and remember he can't miss because of 'true strike ' then it's victory assured.
There are probably ways to beat this especially with a 2 mana summoner, but I think I'd risk this again as a strategy going fowards. There might even be a better single monster I can play for this rule set.
For now it's a nice cheek win.
