{"ops":[{"insert":"That looks really well put together. I actually had to come through it a few times to comecup with any notes. \n\nLet's talk mana base. I love that you're packing 39 lands, and you have more than enough color fixing. The only bad pick I see is Reliquary Tower; it's actually bad for your commander. You can leverage hand limit to discard a card for your commander's cost reduction, but not if the tower is in play. Most decks don't need more than 7 cards in hand to win anyway.\n\nI would swap Reliquary Tower Temple of Epiphany, Exotic Orchard and maybe one of each basic land for more utility lands.\n\nEdit: Here's a funny way to play Eris. Sandbag land drops to intentionally discard your 8th card. You'll be down a lands, which sucks, but if you discard Instants or Sorceries, then you're actually ramping toward casting Eris.\nTurns 1-2 skip land drops and discard spells that cast 3 or more mana. You get 4 mana of cost reduction. Turn 3 make a land drop, cast a 1-drop. Now you're at 6 mana of reduction. Turn 4 make a land drop, cast a 2-drop for 8 mana of cost reduction. On turn 5 you're casting your commander multiple turns ahead of curve, with a full grip to start making dragons on turn 6. \n"}]}
