I am Decay (Gold)

If you control a [Pestilence] Contender, this card costs G less to play.
Discard two cards, then draw two cards.
If the Portal is open, distribute X Toxic Counters among any number of target Clash cards you don't control, where X is equal to the number of cards you've discarded this turn. Until end of turn, [Harbinger symbol] Clash cards you control get +0/+1 for each Toxic Counter distributed this way.
