Good read indeed. The past few top8s all included some number of painterblast decks as soon as the card was legal. I think this card broke the metagame wide open. I'll quote a passage from your article and would like to elaborate on that:
With this trend comes a niche created to exploit the heavy Blue presence, and this exploitation has most recently come in the form of main deck Red Elemental Blast and Pyroblast. As a cheap and efficient answer to cards like Gush, Force of Will, Mana Drain, Flash, Merchant Scroll, and Tidespout Tyrant, this is truly the heyday of 'Red Blasts.'
The common complaint (although I had never shared it) since the unrestriction of gush and flash enabled was that blue cards (everyone arguing for others) were too broken:
4x brainstorm
x ponder
4x merchant scroll
4x flash/gush
were (and are) in almost any deck, together with blue cheap or free disruption:
4x Force of will
some misdirections or pacts.
The only things rebs didn't hit were basically (in those decks)
acceleration
duress
most permanents (tyrant and tinker yes)
reb+painter is the nuts in that meta, and it ruled the last two weeks apparently.
Of course, there was ichorid and brown around, but those two strategies can be hated specificly with a sample sideboard of
4x leyline
3x extirpate/needle
3x ingot chewer
3x rack and ruin
2x explosives
With the heavy apperance of oath I saw creature strategies as subpar before.
The logical point now for me is that aforementioned strategies will be under heavy strain in the near future, causing the metagame to shift to nonblue strategies (not that hose would disappear, packing own rebs is broken.)
Another thing it will mean in upcoming tournaments is that you can expect the metagame to adjust slightly. As a knee-jerk reaction, you'll probably see fewer people playing Blue in general, and particularly less Tyrant Oath and less Flash. You'll probably see more Manaless Ichorid, more Workshop Aggro, more MUD, more Goblins, and far more decks packing both Duress and Thoughtseize.
(agreed.)
For me, the question is if players still stick to blue based shells, including own reb painter packages, together with the strong colorless finish, or if they go more into the vroman/ sphere/ control or combo/mud direction.
I could see emerging a fast combodeck using painter/grindstone/belcher as well or other strategies, such as RG beatdown rise up (especially if there is less oath)
This card brought us a new contender I think. How fast and how extreme will the metagame shift be?
