Goblin Artisans (Italian) - "Artigiani dei Goblin" [Renaissance]

T: Use this ability only when you cast a target artifact spell; play this ability as an interrupt. Flip a coin; target opponent calls heads or tails while coin is in the air. If the flip ends up in your favor, draw a card. Otherwise, counter your artifact spell. More than one Goblin Artisans ability cannot target the same artifact spell.
