What do you think about Imperial Seal?
And if you go down the rabbit hole of unrestricting Imperial Seal, can you also unrestrict Vampiric and Mystical Tutor?
My thought is that Imperial Seal doesn't see play and I don't think it's because you cannot play 4. If you were to unrestrict all the topdeck tutors, how many would you really want to play?
Those are good questions, that have complicated answers I can't begin to fully unpack here.
I will say, however that two key variables are whether Probe stays restricted and whether Misstep is eventually restricted. The topdeck tutors are much more dangerous if Probe is unrestricted, but less dangerous if Misstep is unrestricted.
The upkeep Vamp play is sufficiently insane that I don't think it can ever be safely unrestricted.
@Smmenen I'm not terribly convinced that Flash would have a good matchup against Workshops if it were unrestricted. Phyrexian Revoker and Walking Ballista are both creatures that were not printed before Flash was restricted and both of them can stop the Reveillark kill. I have a hard time imagining that Disciple of the Vault is good enough to avoid this weakness (too much deck space), but maybe? Is there perhaps other viable Flash kills enabled by newer printings that haven't been explored?
Yeah - I should have been more explicit about this earlier, but I think we'd have more Rector Flash or other novel/different combos than we had in the past in addition to the ones used in the past. Since no one has really worked on Flash since the banning/restriction, there is a good chance that superior kills exist than were used in 2008. And certainly ways to overcome the normal obstacles in the format.
And, if your suspicions are right that Flash would have a bad Shop matchup, then all the more reason that Flash shouldn't be restricted at all.
