MTG New Phyrexia Uncommon Enables Turn 2 Kill

Hammer Time is a popular MTG Modern deck. Attempts to bring the deck into Pioneer have been met with mixed success. Saffron Olive made a Pioneer Hammer Time build on the 28th of May 2022. The content creator piloted the deck in five games, winning three of them. He concluded:

“I view this build as more of a starting point for the archetype than a finished product, so feel free to do some brewing and make some upgrades. But in the long run, I think it’s very possible that Hammer Time could end up as a real archetype in the format [Pioneer], if not tier one, then at least as a playable and fun lower-tier option!”

Phyrexia: All Will Be One will give Hammer Time decks two new cards which may enable the strategy to work in Pioneer. These new cards also grant the deck a potential two turn kill.

The first of these new cards is Kemba, Kha Enduring Kemba, Kha Enduring Whenever Kemba or another Cat you control enters, attach up to one target Equipment you control to that creature.
Equipped creatures you control get +1/+1.
{3}{W}{W}: Create a 2/2 white Cat creature token. . A two mana 2/2 Cat Cleric, when Kemba Kha Enduring, or another Cat, enters play under your control you can attach a piece of equipment to them for free. Kemba, Kha Enduring can grab the hammer upon entering the battlefield. This card also synergizes nicely with several powerful Cats already in Pioneer. The card Lion Sash Lion Sash {W}: Exile target card from a graveyard. If it was a permanent card, put a +1/+1 counter on this permanent.
Equipped creature gets +1/+1 for each +1/+1 counter on this Equipment.

Kemba, Kha Enduring also grants all equipped creatures you control +1/+1 and allows you to create a 2/2 cat token for five mana, abilities which are nice bonuses.

Kemba, Kha Enduring’s reveal got the community on Reddit very excited about the possibilities of Hammer Time in Pioneer…

“Kemba could singlehandedly make Hammer a thing in Pioneer. I mean not singlehandedly but you know what I mean.” Exploringdeathntaxes

“It could be a t3-t4 win.” D-fakkr
