Alright so here's the thing:
Dim. Shield lasts 3 turns. You can have 6 of them. 6*3= 18 turns of damage immunity.
Most decks have 30 cards, draw 7 or 8 on turn 1 and 1 card per turn after that. Thus, a "standard" deck will deckout in 24 turns.
The difference is only 6 turns. If your opponent packed Dim. Shield and you don't have PC/momentum you have 6 turns to kill them in, and that's assuming they have no other stall.
But where this gets really broken it the arena.
Let's discuss the deck doubling dexterity dodad. Suddenly they go from having 18 turns of damage immunity to 36.
Furthermore, if they have a 2x or 3x mark they will have enough quanta to summon the next shield by the time their old one expires from their mark alone.
Mono is currently hyper-dominant in the arena right now, to the point that I'm seeing a lot of "dead card" mono where the deck builder simply ignored the oracle card and built a monoaether with 5 unplayable cards. Many of these decks are even performing fairly well
Hyper dominant in arena? Hardly. The reason they do well in bronze and silver is people A: Don't know what they are doing still: B: testing stuff out: C: bad draws,(lost a lot do to them) Gold and plat don't see very much mono aether at all. Especially plat, where its actually pretty bad.
Aye. The meta in bronze+silver is so much different than in gold+plat, both in decks played and decks submitted.
There are essentially 3 metas in the game, excluding things like tournament metas and whatnot): Bronze/Silver, Gold/Plat (arguably they should be split), and PvP.
In low tier arena, people use Dims because they don't know what else to use yet. Many are still learning the game. A handful of others use it because it works against others who don't know what they're doing either.
In high tier arena, people don't use Dims hardly at all because there are so many more effective things, and most decks people bring into plat either have heavy control or bypass shields with poison.
In PvP, Dims (and by extension
) is used because it works. It's largely about predicting what will work and what won't against your opponent's deck. Here's a a flowchart:
Is opponent going to play a rush?
-Yes: Are you going to have
in your deck at all?
--Yes: Consider Dims.
--No: Don't use Dims.
-No: Probably don't use Dims.
....This post kind of went from talking about Dims to metas but it's still about Dims so whatever.
