The Grandmaster's is capable of traversing space, time and the dimensions. The Grandmaster’s standard method of playing games are to choose a team of champions to do combat with another team selected by his opponent.

So do we get to see Asgardians vs Kree vs Planet Xander vs Guardians of the Galaxy vs Thanos?

Although the Grandmaster can resurrect most living beings after their deaths, he cannot do so with virtually immortal beings like himself who are killed. The Grandmaster once challenged Death itself to a game. If Grandmaster won, then the Collector would live, but if he lost, then he too would also die. The Grandmaster and Death each selected teams from among Earth’s superhumans to do battle in a contest of champions. The Grandmaster’s team won, but Death revealed in order to bring the Collector to life, the Grandmaster would have to forfeit his own life. Compelled by his sense of gamesmanship to see the game through to its end, the Grandmaster died and the Collector returned to life.

However, Death then challenged the Collector to a game, apparently with the resurrection of the Grandmaster as the stakes. The outcome of the game is unknown, but the Collector is known to have survived and the Grandmaster has been seen since. The Grandmaster then used the Avengers and an incarnation of the Legion of the Unliving in another contest against Death, in which he won immortality for himself and all of the Elders.

Interesting.

Later the Elders of the Universe plotted to kill Galactus by using the Infinity Gems against him. This plan failed and the Elders were then confronted by a power seeking Thanos. The Grandmaster lost one of the gems in the process, and Thanos gained ultimate power shortly thereafter.

Possible Plot Spoiler?
