Kozilek, Compleated

Two of Magic's most infamous keyword mechanics get fused into one on this titan, and the collision is the whole design. Annihilator was the Eldrazi step that made attacking with a colossus an act of removal, forcing sacrifices whether or not the swing ever connected. Poison, meanwhile, has always been the slow-clock alternate win condition: a resource that accrues on the opponent but rarely threatens the board directly. Annihinfect welds the two, so every poison counter the defending player carries becomes a permanent sacrificed the moment this attacks, no combat damage required. The cast trigger primes that engine before the body ever swings, planting two poison counters up front so the first declaration of attackers already strips two permanents, and stapling on a hand-disruption clause that drags opponents down to two cards while the spell is still on the stack. Then the mana cost delivers the compleation gag literally: the two hybrid Phyrexian pips can be paid in life, so a titan that is colorless by nature and alien by design gets to phyrexianize its own casting cost. This is a maximalist top-end built to be read and grimaced at rather than assembled around, an answer to the question of what happens when you refuse to pick one broken keyword and fuse several into a 12/12 that shreds hands on the cast and boards on the swing. The only restraint is the ten mana value and the need to survive a turn with it in play; everything downstream of that is designed to feel unfair on purpose.
