As usual, there are some potentially very impactful cards hidden in the final bunch of spoilers. One of them could very well be this one.
I didn’t really expect that to be back any time soon, as they have recently nerfed this ability somewhat, but it is a good answer to Eternalize. However, in Standard, just the tempo can also be important.
Early last year, there was a deck played by Tomoharu Saito which this is somewhat based on. I loved that deck and won a PPTQ with it (for once I didn’t even change the sideboard). It might be quite weak against [card]Magma Spray[/card], but it seems to me that not that many people play it.
We have lost a couple of important cards from the previous version. First, the [card]Shivan Reef[/card] was an excellent way to activate [card]Dimensional Infiltrator[/card] and also screw with scrying. Also, [card]Exquisite Firecraft[/card] was an excellent way to end the game against certain decks that would bring in countermagic, and dealing four is just great as well.
4 Dimensional Infiltrator
4 Stormchaser Mage
4 Nimble Obstructionist
4 Fevered Visions
4 Incendiary Flow
4 Collective Defiance
4 Spell Shrivel
4 Wandering Fumarole
4 Inspiring Vantage
Actually, one might want to exchange a couple of the Mountains for the new red painlands for the Infiltrators. I’m not sure how many, exactly. Also, [card]Shock[/card] might be a good replacement for one of the other burn spells. Stealing initiative with it in the early game can be quite good.
I’m not totally sold on [card]Stormchaser Mage[/card]. There are other options. The earlier version played [card]Goldnight Castigator[/card]s, but that might not work out here. Other options might include [card]Glorybringer[/card] or [card]Skyship Plunderer[/card], even though we don’t have any way to abuse the latters ability in the deck. Maybe with a planeswalker, like [card]Chandra, Torch of Defiance[/card], in the sideboard?
