Viruspell

Description
Fire a shot for 20 damage and add a duplicate to your deck. Anchor.

Strategy and Synergy
Viruspell's duplicating power can augment the strength of spells like Deck Slam that depend on deck size. In a deck featuring few other cards, it can also act as a steady source of damage.

Viruspell goes well with artifacts that trigger an effect on casting a spell, but will erode the effectiveness of decks relying on the more it multiplies.

Viruspell keeps its upgrades when it multiplies. Upgrading this spell is recommended.

See Viruspell Deck.

Trivia
The flavor text is a reference to the song "You're the one that I want" in the 1978 movie Grease.
