Laboratory Maniac

Vigilance Adeline's power is equal to the number of creatures you control. Whenever you attack, for each opponent, create a 1/1 white Human creature token that's tapped and attacking that player or a planeswalker they control.

When this creature enters, you may search your library for a creature card with mana value 1 or less, reveal it, put it into your hand, then shuffle. Sacrifice this creature: Your opponents can't cast noncreature spells this turn.

Whenever you cast an Aura, Equipment, or Vehicle spell, draw a card.

Counter target spell.

When Urza enters, create a 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control." Tap an untapped artifact you control: Add U. 5: Shuffle your library, then exile the top card. Until end of turn, you may play that card without paying its mana cost.

Flash (You may cast this spell any time you could cast an instant.) When Venser enters, return target spell or permanent to its owner's hand.

You may look at the top card of your library any time. You may play lands and cast spells from the top of your library. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost. T, Sacrifice ten nonland permanents: Each opponent loses 10 life.
