[confirmed]Proliferate chooses which counter on permanent/pl

by **FastEddie** » 27 Apr 2020, 16:01

Describe the Bug:
Contagion Engine proliferates also poison counters the opponent has. Also, when choosing "Auto mode" I get asked for every type of counter.

Which card behaved improperly?
Contagion Engine.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Version 3-2020 9e576b6
Duel

What exactly should be the correct behavior/interaction?
Opponent's poison counters should not be increased. Auto mode should proliferate all types of counters without further asking.

Are any other cards possibly affected by this bug?
All cards with Proliferate mechanic.

Contagion Engine's activated ability should increase poison counters as any other counter a player can have. ~~In fact I see that it can't choose a player with poison counters on manual mode while it should.~~ On auto mode it adds too many counters on players. ~~And prompts twice.~~ wrong

From the Comprehensive Rules (April 17, 2020—Ikoria: Lair of Behemoths)

701.26. Proliferate
701.26a To proliferate means to choose any number of permanents and/or players that have a counter, then give each one additional counter of each kind that permanent or player already has.

Fixed that proliferate cards added too many counters when choosing auto to players in fc69c5f.

In War of Sparks the rules changed and you can't choose which counters on permanent cards to proliferate but only which permanent or player. This has to be implemented for auto and manual choice.
