With Xanian Spellbook open, Invoke permanently replaces cards and visually bugs them

[queen igloo]

• I open Spellbook after casting Combustion (2:15)
• It invokes, replacing the 4th spell (Chain Lightning) with a 3-cost Rammer (the spell that was in that hand position was Morgrul's Mark, so a Rammer makes sense)
• I go to play that minion, except it actually plays the Chain Lightning at a 1-mana discount (instead of the 2 that the spellbook should provide)
• Then, a full cost Rammer is in the 4th slot in my hand
• After cycling my deck, Rammer is there, having permanently replaced Morgrul's Mark in my deck

another copy of this happening (mark got replaced with a 2-cost wheel of doom)

Have you thought about not Combusting whilst the book is open?

[queen igloo]

i have! however, science

also my brain autoplays the book the instant it hits my hand

tbf fdm could've just thought about releasing it without a bug

[brazen forge]

for science: what happens when you invoke it MORE than once?

[queen igloo]

presumably it's a regular minion afterwards, so it goes 1 more up the mana cost chain

yes this means you could theoretically get a hand full of permanent 10 mana mar'dreds; yes I tried this; yes I got bored and gave up 😅

[brazen forge]

well there is worse

you could get 4 frozen rimargaals

[queen igloo]

not with this bug

[brazen forge]

well, dont need a bug for that
