Hideaway 5 (When this artifact enters, look at the top five cards of your library, exile one face down, then put the rest on the bottom in a random order.) 1, T: Put a +1/+1 counter on target creature you control. Then if you control three or more creatures with different powers, you may play the exiled card without paying its mana cost.

During your turn, your opponents can't cast spells or activate abilities of artifacts, creatures, or enchantments.

Whenever you cast a creature spell, choose one — • Create a 1/1 colorless Gnome artifact creature token. • Create a token that's a copy of target artifact token you control.

When this enchantment enters, exile all graveyards. If a card or token would be put into a graveyard from anywhere, exile it instead.

Whenever you sacrifice this artifact or another artifact, you may pay 2. If you do, at the beginning of the next end step, create a token that's a copy of that artifact. 2, Sacrifice this artifact: Draw a card.

When this artifact enters, scry 2. Whenever another artifact you control with mana value 3 or greater enters, create a 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control."

If you would create one or more artifact tokens, instead create those tokens plus an additional Map token. (It's an artifact with "1, T, Sacrifice this token: Target creature you control explores. Activate only as a sorcery.") 1U, T: Create a token that's a copy of target artifact token you control.

When this enchantment enters, you draw three cards, gain 6 life, and create three 2/1 black Bat creature tokens with flying. At the beginning of your end step, you discard a card, lose 2 life, and sacrifice a creature. When this enchantment leaves the battlefield, you discard three cards, lose 6 life, and sacrifice three creatures.
