Meren toolbox/combo is the name of the game. I am still 1 Verdant, 1 Misty, 1 Bayou and 1 Wasteland short of what I would consider optimal, but this is the version of the deck that I am playing right now.

The general game plan is to disrupt my opponent enough and clear the way for a big beater. Your most common plan of attack will be to edict an opposing creature with plaguecrafter/merciless executioner/fleshbag maurader then start repeating that plan with Meren in play. Maybe 5% of your wins will come from actually combo-ing off with Mike and Trike or Mike, walking ballista and any unconditional sac outlet. Individually these cards contribute to your overall game plan anyway so including the combo comes at a very low cost. An early buried alive into mike and trike in the yard can have your opponent jumping through hoops to avoid being combo-ed out, which opens up room to grind your opponent out value creatures and Meren.
