At the beginning of your upkeep, you may search your library and/or graveyard for a Shrine card and put it onto the battlefield. If you search your library this way, shuffle.

If an ability of another Shrine you control triggers while you control six or more Shrines, that ability triggers an additional time.

Legendary creatures you control get +X/+X, where X is the number of legendary creatures you control.

If you would lose unspent mana, that mana becomes black instead.

At the beginning of your first main phase, look at the top card of your library. You may reveal that card if it has three or more colored mana symbols in its mana cost. If you do, add three mana in any combination of its colors and put it into your hand. If you don't reveal it, put it into your hand.

Gen gets +1/+1 for each different year of release among other nontoken permanents you control. (For example, if a card was released in 1993, that's one year of release. Specific editions matter.)

Whenever Gen attacks, if its power is 30 or greater, you win the game.

Whenever you cast a signed spell or play a signed land, copy it. (A signed card is a card signed by its artist, designer, or someone else it's strongly associated with.)

Discard a signed card: Destroy target creature with a name that has a five or fewer letter length difference from the person who signed the discarded card.
