I sacrifice these cards to the Dwarven Forge and use it to empower my Thunder Berserker and transform him into THOR, GOD OF THUNDER! Next I have him mount my Black Dragon and use him to attack your Tark! Whilst that's happening, I place down Wastage. This causes the last monster who attacked me to have their attack and defence reduced and leaves it vulnerable to being attacked by anything.
*Thor promptly strikes mamibo's Tark whilst I draw new cards*
In order to conceal what I have from enemy attacks, I take a 5 of gaze and cover it with the six of swarm, creating a venomthrope, a creature which protects others in a toxic cloud which can't be seen through easily.
So hey, I'm back, again, but I don't think I will stay here for long. Anyway, I saw that you were trying to defeat Tark (or something like that) and since you said there are no rules I thought I could join in. Ahem...
