Very solid
It is a rite of passage to let a CoCo player smack you out of existence with their small army they conjured up for 4 mana and it is a lesson in deckbuilding to prepare against these matchups
Madam Mim, Foxs Chasing the Rabbit ability allowed me to return a character from the board to my hand, which meant I could bring back damaged ones or trigger powerful effects from cards entering the battlefield over and over - when Merlin, Goat, which gains a lore each time it enters and leaves the battlefield, turns up you can see where the game really starts
Protecting Marton The downside to Marton is that his ability doesnt boost himself, and hes just a 1/1 charging into battle boosting all your other attacking or blocking creatures
His strategy is aristocrats, where you win by sacrificing your own creatures
Also great for collecting lore is Magica De Spell The Midas Touch, which similarly costs seven ink to play, but once exerted, will allow you to gain lore equal to one of your items in play
