Any plan for if you run into some hasty powerhouses after tapping out for the Crush of Tentacles? For example, your opponent uses Skywhaler's Shot to kill your octopus then runs out a Fleetwheel Cruiser and/or pumps some 3/1's from Chandra, Flamecaller.
The plan is to
fog every turn. Both
Chandra, Flamecaller and
Fleetwheel Cruiser are ruled out of the game if you can keep up throwing 1
fog per turn. To be able to do that, you draw cards. So that's why the whole deck is carddraw and fogs and some board clears that wins us a turn too.
Once you get your hand on
Seasons Past again, you get:
2 mana spell:
fog or 3-4 carddraw
Take Inventory3 mana spell:
fog4 mana spell:
engulf the shore (in a way, also
fog),
dovin baan (lifegain and draw)
5 mana spell: possibly AoE
6 mana spell:
Crush of Tentacles again.
So the math is: statistically, you will always have
fog in hand every turn in lategame.
Now that leads to the question: How do we win? When it's only 2 cards in our library (both are
Seasons Past, because they go there upon resolution), you can cast each turn:
Seasons (6 mana) ->
Crush (5 mana) -> Dovin (4 mana) ->
Fissure (5 mana
awakening), attack. Their turn, 2-mana
fog of your choise. 22 mana total, and you have 23 lands besides
Evolving Wilds.
Repeat until you win.
