watch out for the blue mythic adventure :^)The wrath is top tier, a free threat that doesn't take up room is incredible for control. It's not unusual to have a lot of mana and no proactive plays to make.
Now if only we could get a good counterspell, there should be one left but as long as Teferi is in Standard we may have to settle for Mystical Dispute...
Finkel for me, more consistent finishes and a lifetime winrate 1-2 percentage points higher. The pros seem to see him as a level above even the other great players, as well: like I think Kai might even say he considers Finkel a better player.
not all games involve drawing perfectly or normally
Some parasitic mechanics are fine, especially when, like you mentioned, these cards are aimed solely for Limited.
...there you go. This is the kind of win condition Control really wants. Nobody wants to pay 7 mana at sorcery speed for a 7/7 vanilla. You would much rather pay 5 mana at instant speed for 1/1 vanilla that's attached to a land.
People seem to be playing it in the Arena 2020 Standard event and it's still working out most of the time. Mana is definitely more shaky but it's not impossible. Shards are definitely in a worse spot than wedges with only one relevant temple though, that's for sure. I think a control deck like Esper that gets to run like all of the sweepers may still be able to make it work.
