The copy cannot be played on the same turn that it is created, despite having full mana. Similar cards that can give a card full mana (such as a card drawn with Talent of the Telepath that costs 6 or less mana, or a copy of a creature from Metamorphic Alteration that costs 10 or less mana, or a full mana card drawn from Djinn of Wishes' support being broken on the same turn) will play the copy or fetched card on the same turn, so Quasiduplicate's behavior is inconsistent with existing mechanics of the same type.In addition, a bonus match still will not result in the copy being played.For example: I match 5 and cast Quasiduplicate on Traxos, Scourge of Kroog. I get a copy of Traxos in my hand with full mana. This copy is not played. I gain a bonus match from my match 5 and I make another match. Copy Traxos with full mana is still in my hand, and it is not played even after this bonus match.This bug occurs when Quasiduplicate is cast on any creature that I have tried (I tried 4 different creatures), as well as on different Planeswalkers (tested on Karn and Tezzeret, Master Artificer).
Tombstone said: I discussed this with the team, and they have informed me that this behavior is as designed. Copied cards are not intended to be able to be played on the same turn; however, Fetched cards are so Talent of the Telepath and Djinn of Wishes are functioning as intended. The team is aware of inconsistencies with cards that create Copies being able to be played on the same turn such as with Metamorphic Alteration and they are currently investigating. Moving forward though, Copies are not intended to be valid for play on the turn they are created according to my information.
