mtg tarkir dragonstorm precon commanders The 15 Best New Cards from the Commander Precons border cards Wizards of The Coast Magic:

If the number of historic cards in your graveyard changes while activating mana abilities, the cost to cast The Capitoline Triad remains what you previously determined

I wouldnt recommend putting Ox of Agonas in just any deck, though

Cutthroat Negotiator Our fifth card for the deck brings us our only Parley in Cutthroat Negotiator

The more lands you have untapped, the more mana you have to flip over manifested cards

Sidisi, Undead Vizier Perhaps unsurprisingly, Sidisi, Undead Vizier lends itself well to combo shells that rely on Sidisi exploiting creatures to find cards like Ad Nauseam or Doomsday

So far these decks are looking to be fairly well put together out of the box, even if the land counts seem a tad high
