Whenever an opponent casts a spell, you may draw a card unless that player pays {1}.

Equipped creature gets +1/-1. Whenever equipped creature dies, draw two cards. Equip {1}

+1: Look at the top five cards of your library. You may reveal an artifact card from among them and put it into your hand. Put the rest on the bottom of your library in any order. −1: Target artifact becomes an artifact creature with base power and toughness 5/5. −4: Target player loses X life and you gain X life, where X is twice the number of artifacts you control.

At the beginning of your upkeep, if you control an artifact, create a 1/1 colorless Thopter artifact creature token with flying. Whenever one or more artifact creatures you control deal combat damage to a player, draw a card.

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.
