MTG >Combos >Prototype Portal +Ugin's Nexus +Bosh, Iron Golem +

You need Bosh in play, the prototype portal and Ugin's Nexus in hand (or the prototype portal in play with Ugin's Nexus imprinted). 1- Play the prototype portal and imprint Ugin's Nexus from your hand, then create a token of Ugin's Nexus with the activated ability of the prototype portal. 2- Sacrifice the token to Bosh and deal 5 damage to any target. 3- You will get an extra turn because of the triggered ability of Ugin's Nexus. Then create a token again and sacrifice it to Bosh. 4- Repeat this process until the game is over.
