Connecting the Dots

Flying, vigilance, haste Whenever a player attacks with three or more creatures, you draw a card. Whenever a player attacks with five or more creatures, Aurelia deals 3 damage to each of your opponents and you gain 3 life.

Return up to one target artifact card, up to one target land card, and up to one target non-Aura enchantment card from your graveyard to the battlefield. They are 5/5 Elemental creatures in addition to their other types.

As an additional cost to cast this spell, collect evidence X, where X is the total mana value of the permanents this spell targets. Destroy up to one target artifact, up to one target creature, up to one target enchantment, and up to one target planeswalker.

Flash Flying Artifacts and creatures entering don't cause abilities to trigger.

Vigilance When Alquist Proft enters, investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.") XWUU, T, Sacrifice a Clue: You draw X cards and gain X life.

Double strike, vigilance Whenever Agrus Kos enters or attacks, choose up to one target creature. If it's suspected, exile it. Otherwise, suspect it. (A suspected creature has menace and can't block.)

Whenever you cast an artifact spell, investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.") Activated abilities of artifacts you control cost 1 less to activate. This effect can't reduce the mana in that cost to less than one mana.

Creatures you control get +1/+1. Whenever a creature you control enters, this enchantment deals 1 damage to each opponent.
