I think I didn't understand what it does
cast any of the listed alchemist card and
you get a free ability of +2/+2 to target creature of your choice.
Then where would you use it? I mean, why would just a small buff be so important to occupy a weapon AND shield slot?
it makes decks that revolves around alchemist cards more powerful,
for a 1 other quanta, each of your alchemist cards have almost doubled the power/effects.
instead of doubling alchemist cards effect,
i chose +2/+2 instead as its a buff that can be more generally applied to most creatures in favour of player.
Deathstalker, Alfatoxin combo (deathstalker attack and poison)
Otyugh, Black Hole combo (otyugh buff)
Iridium Warden, basilisk black combo (buff your iridium warden to creature attacker)
forest scorpion, adrenaline combo (12 damage per turn, 2 poison per turn)
pegasus, luciferin combo (pegasus buff to dive)
dejavu precognition combo (dejavu clone gets +4/+4 in total)
minor vampire liquid shadow combo (minor vampire double stats)
