Trample

Alexios, Deimos of Kosmos attacks each combat if able, can't be sacrificed, and can't attack its owner.

At the beginning of each player's upkeep, that player gains control of Alexios, untaps it, and puts a +1/+1 counter on it. It gains haste until end of turn.

Haste

When Kassandra enters the battlefield, search your graveyard, hand, and library for a card named The Spear of Leonidas, put it onto the battlefield, then shuffle.

Whenever a creature you control with a legendary Equipment attached to it deals combat damage to a player, draw a card.
