The same here

Lost two games of Premier Draft because Argentum Masticore's triggered ability didn't resolved as intended. After discarding a card to it at my upkeep, it should destroy a nonland permanent from my opponent, which it happened as if it wasn't any legal targets on the field.
Until matters resolves, I'm not going to play any more drafts, knowing that my bomb rare is not going to function as intended.
Please,fix this.

Lost in sealed from this. Can you please refund?

argentum masticore not working,. i lost a game becasue of that.

I just lost a sealed game as well from this bug

Argentum Masticore discards without adding the ability to destroy a target.

While playing Quickdraft, Argentum Masticore's ability repetitively causes me to discard, but does not trigger the removal option despite more than single legal target. I have lost a game in draft due to this and I am very displeased.

I am playing on PC.

The discard doesn't allow targeting permanent. Lost me several matches in quick draft

Exact same thing happened to me.

As many others lost draft games to Argentum Masticore not triggerig after discarding several cards even thou opponnet had many cards onbattlefield with mana value lees than card discarded

Argentum Masticore is bugged and as a result I lost more than 1 game while playing a Quickdraft Event.

Also lost a draft game to Argentum Masticore upkeep delayed trigger not going on the stack.

At the beginning of upkeep, discarded a card with cmc=3, no trigger popped up even though my opponent had multiple non-land permanents with mana value 3 or less.
Following turn, discarded a land card, no trigger popped up despite my opponent controlling a token.

I'm affected by this also.

The same happened to me in draft.

Using Arena app on mobile, Aregentum Masticore did not let me select a creature permanent of same mana value or less after discarding a card. I'd appreciate to know when this is fixed, so I don't have to draft around it, and some crystal reimbursement for the draft. Thank you!

Playing the premier draft after the update my Argentum Masticore didn’t work properly, so I discarded multiple cards to it and lost the game

The same happened to me, also in draft. I discarded a card with mana value 5 and could not destroy the token or the creature with mana value 3 my opponent had.
And it also happened in draft for me and caused me to lose...

100 % of time not processing here...

Same. In a game it's only a game lost, but in draft, we lost 1500 gems.

Lost multiple games to the discard trigger not allowing me to select an opponents creature to destroy, just immediately passed the trigger upon discard and cost me the game.
