March of the Machine Commander

Backup 1 (When this creature enters, put a +1/+1 counter on target creature. If that's another creature, it gains the following ability until end of turn.) Whenever this creature attacks, double the number of +1/+1 counters on target creature. That creature can't be blocked by creatures with power 2 or less this turn.

Whenever you cast a Phyrexian creature or artifact creature spell, incubate X, where X is that spell's mana value. (Create an Incubator token with X +1/+1 counters on it and "2: Transform this token." It transforms into a 0/0 Phyrexian artifact creature.) At the beginning of each end step, if a Phyrexian died under your control this turn, proliferate.

Artifact creatures you control have trample. At the beginning of your end step, create a 0/0 red Gremlin artifact creature token. Put X +1/+1 counters on it, where X is the number of differently named artifact tokens you control.

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for 1 or one mana of that creature's color.) Flying, vigilance, haste Whenever you cast another spell that has convoke, scry 2, then draw a card.

Eminence — Whenever you attack with one or more Knights, if Sidar Jabari is in the command zone or on the battlefield, draw a card, then discard a card. Flying, first strike Whenever Sidar Jabari deals combat damage to a player, return target Knight creature card from your graveyard to the battlefield.
