: Add . : Until end of turn, Frostwalk Bastion becomes a 2/3 Construct artifact creature. It’s still a land. ( can be paid with one mana from a snow source.)
Whenever Frostwalk Bastion deals combat damage to a creature, tap that creature and it doesn’t untap during its controller’s next untap step.
A creature dealt combat damage by Frostwalk Bastion won't untap during its controller's next untap step, even if it was already tapped and even if Frostwalk Bastion leaves the battlefield before then.

If you turn Frostwalk Bastion into a creature but haven't controlled it continuously since your most recent turn began, you won't be able to activate its mana ability or attack with it.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
