Enchantement
Quand l'Alchimie artérielle arrive sur le champ de bataille, créez un jeton Sang pour chaque adversaire que vous avez.
Les jetons Sang que vous contrôlez sont des équipements en plus de leurs autres types et ont « La créature équipée gagne +2/+0 » et équipement

.
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.
