Tidal (This permanent is Aquatic if there more Aquatic permanents on the battlefield. This permanent is Aerial if there are more Aerial permanents on the battlefield.)
As long as Glarstcire Stormcaller is aerial, Glarstcire Stormcaller has "Remove a Sky counter from any creature and sacrifice Glarstcire Stormcaller: Deal 4 damage to target creature."
As long as Glarstcire Stormcaller is aquatic, Glarstcire Stormcaller has "Sacrifice a water token and Glarstcire Stormcaller: Counter target noncreature spell."
This is the worst iteration of tidal, since tidal is itself already a hoop to jump through and this piles more hoops on top of them.
Water tokens being aquatic seem especially redundant.
Removed "As long as Glarstcire Stormcaller is aerial, sorceries you cast cost less if Glarstcire Stormcaller has a sky counter. As long as Glarstcire Stormcaller is aquatic, instants you cast cost less if you control three or more Water tokens."
