Grell Philosopher

Type line

Creature — Horror Wizard

Oracle text

Aberrant Tinkering — When this creature enters and at the beginning of your upkeep, each Horror you control gains all activated abilities of target artifact an opponent controls until end of turn. You may spend blue mana as though it were mana of any color to activate those abilities.

Rulings

• Grell Philosopher causes Horrors to gain only activated abilities. They don't gain keyword abilities (unless those keyword abilities are activated), triggered abilities, or static abilities.2022-06-10
• Activated abilities contain a colon. They're generally written “[Cost]: [Effect].” Some keywords are activated abilities and will have colons in their reminder text.2022-06-10
• The granted abilities effectively use “this permanent” rather than “[that card's name],” so you treat the abilities as if they were printed on the creature that gained the ability. For example, say the artifact was Universal Solvent, which has the ability “, , Sacrifice Universal Solvent: Destroy target permanent.” If Grell Philosopher gained that ability, you'd treat it as though it said “, , Sacrifice Grell Philosopher: Destroy target permanent.”2022-06-10
