Incantesimo
Quando l'Alchimia Arteriosa entra nel campo di battaglia, crea una pedina Sangue per ogni avversario che hai. (È un artefatto con "

,

, Scarta una carta, Sacrifica questo artefatto: Pesca una carta".)
Le pedine Sangue che controlli sono Equipaggiamenti in aggiunta ai loro altri tipi e hanno "La creatura equipaggiata prende +2/+0" ed equipaggiare

.
If a Blood token is somehow both a creature and an Equipment, it can't be attached to a creature.
If you control more than one Arterial Alchemy, creatures equipped with Blood Equipment will get +2/+0 for each Arterial Alchemy. The equip cost is still
.
Blood tokens stop being Equipment if Arterial Alchemy leaves the battlefield. If any of them are attached to creatures at that time, they become unattached.
You can't sacrifice a Blood token to pay multiple costs.
If an effect refers to a Blood token, it means any artifact token with the subtype Blood, even if it has gained other subtypes.
Some triggered abilities trigger "whenever you sacrifice a Blood token." These abilities trigger regardless of why you sacrificed that Blood token.
