Quote from Shiftrex »The lifegain seems to really help this deck out. Have you considered the Ajani's Pridemate package? I think I recall the deck that you are being inspired from and he was running a pridemate package so that he had some lifegain synergies and a secondary win condition.
Weight of Memory may be a good card to consider as a mill finisher too because of the Psychic Corrosion synergy. Seal away also seems like really good removal that you are currently passing up. Bounce is nice but getting rid of something if they can't answer enchantments seems worthy of a spot, sideboard for game two if it doesn't work in the matchup but it should see success against midrange.
Quote from D90Dennis14 »As Seal Away can often be a dead card I wonder if maindecking Lightning Strike can be better as it can at least go to the face and make Fight with Fire or Banefire for lethal a bit easier.
Ixalan's Binding would still be in the deck to deal with bigger creatures though with Assassin's Trophy and Knight of Autumn in the format it isn't as permanent a removal as it used to be.
Speaking of Knight of Autumn, I considered maindecking it over Thrashing Brontodon but I'm not convinced yet.
The dino is a better blocker and having the option to remove an artifact/enchantment at will (with a mana open) instead of having to time its EtB ability also seems better.
I've also added copies of Shalai and The Immortal Sun to the SB taking out Chandra which is probably just a win-more card.
Another potentially good finisher I consider for the deck is March of the Multitudes which can work well even without convoke to generate a big board with all the mana this deck can sink into it.
