[duplicate]Deathgrip

by **gnomefry** » 18 Feb 2020, 20:43

Describe the Bug:

Deathgrip is not available for use if the required mana would come from a two-step process such as Urborg, Tomb of Yawgmoth or filter lands like Twilight Mire. When an opponent casts a green spell under these circumstances, Deathgrip doesn't highlight as available and the stack doesn't pause for responses at the interrupt stage.

I'll attach 2 savegames, one with Deathgrip/Urborg and the other with Deathgrip/Twilight Mire. Both saves are just before the AI will try to cast a green.

Which card behaved improperly?

Deathgrip

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink test build Jan 12 2020 - gauntlet

What exactly should be the correct behavior/interaction?

If a green spell is being cast and (2) black mana is available via a two-step process, Deathgrip should highlight as usable and pause at the interrupt stage for a possible response.

Are any other cards possibly affected by this bug?

These are known engine limitations. I can't find the post where Korath mentions that exactly but here are 2 other post about close to above issues:
There is one other that mentions that engine can cope with pay {1}

: produce

and so on.
