Odd effect of liquid shadow + antimatter

[ChemMan13]

Recently I started trying a twist on the old time deck Liquid Antimatter. I came across a possible glitch in the game when playing level 3 AI's. Occasionally, when an opponent's creature that is both antimattered and has the ability vampire, its attack heals me to full HP (100 since i don't use stone skin or shard of divinity in the deck) then proceeds to deal the finishing blow to the AI. The weird thing is I am awarded 42 electrum instead of the standard 40 for a 100 HP EM win against level 3. Is this a glitch, or is the combo supposed to temporarily raise max HP?

It ends on your current HP, then compares it to max. If current is over max, you get a better EM of sorts since it's still applying the electrum for HP calculation.

This also happens with SoSac when a GotP is discarded on the turn the opponent dies by poison (more or less common playing Pdials against ghostmare)

Thanks for the response.
