Offerte Yu-Gi-Oh! - Unstable

State-based actions don't apply to you or other permanents you control. (You don't lose the game due to having 0 or less life or drawing from an empty library. Your creatures aren't destroyed due to damage or deathtouch and aren't put into a graveyard due to having 0 or less toughness. Your planeswalkers aren't put into a graveyard if they have 0 loyalty. You don't put a legendary permanent into a graveyard if you control two with the same name. Counters aren't removed from your permanents due to game rules. Permanents you control attached or combined illegally remain on the battlefield. For complete rules and regulations, see rule 704.)

When Riveting Rigger enters the battlefield, you may sacrifice another artifact. If you do, put two +1/+1 counters on Riveting Rigger and it assembles a Contraption. (Put the top card of your Contraption deck face up onto one of your sprockets.)

Whenever you crank Pet Project, put target creature card from an opponent's graveyard onto the battlefield under your control.

Whenever you crank Optical Optimizer, until end of turn, target creature becomes an artifact in addition to its other types and gains "{T}: Draw a card."

{W}, {T}: Tap target creature without reminder text. (Reminder text is still any italicized text in parentheses that explains rules you already know.)

Flying Novellamental can block only creatures with flying.
