calculation puzzle - "Magic: the Gathering" Challenge #2: Two Peas in a Pod


Previous Challenge


Next Challenge


BACKGROUND:
Here's a puzzle for Magic: the Gathering players out there. I feel that this puzzle is in the scope of the site, and is no different than other puzzles, e.g. chess, which require knowledge of the parameters of a game in order to solve. I'm adding the MtG tag since I hope to do more of these in the future. I've linked to cards so that you don't have to go look them up yourself. For those interested in learning the rules of Magic, see here and here.


I've tried to ensure that there is only one correct answer, but there are so many permutations, I may have missed one. Please don't post an answer unless it's distinct i.e. isn't just another answer but with mana tapped slightly differently or two spells cast in swapped orders if it doesn't affect the outcome. If I missed something, and there are multiple distinct solutions, I will accept the one that gets the most damage through. Your solution cannot involve opponent's cooperation (e.g. they choose not to block any of your creatures) in other words, it must be a guaranteed win regardless of what your opponent can do.


PUZZLE SETUP:
It is Main Phase 1 of your turn. You have played your land for the turn. No cards have been put into either graveyard so far this turn. Defeat your opponent during this turn (before end of cleanup step). Provide the sequence of spells/game actions that you take to achieve the goal. Please be specific about mana usage / land tapping (feel free to keep a count of mana between steps)
