I think Galactus was created by a future Franklin Richards, sent back in time to devour the celestial incubating inside the Earth (like in Marvel's Eternals). He does this to prevent the destruction of Earth - but even with Reed's genius able to relocate the celestial, Galactus' sole purpose must be fulfilled and continues on his path to consume Earth's core.

Reed realizes that the only way to stop Galactus is to remove Franklin Richards from the timeline, thus Reed bringing his family to the main Marvel MCU timeline - saying goodbye to the universe that they are beloved in - and into a world where they (especially the Thing) are far more likely to be perceived as threats and monsters.

End credits bonus: Doom's plan to steal the powers of Surfer/Galactus and become Earth's savior is ruined and he follows them with his time pad to enact his revenge.

This isn't a color pie break because you have to return a land back to your hand. It's not permanent ramp like green, it's a temporary mana increase, more akin to a ritual. Yes, it can be abused and is much better in a landfall deck, but an important note is that you can't play that land even if you haven't played an additional land that turn because it gets returned during your end step.

The water effects in this game are top notch, I definitely want to see him abuse the water and waves, and his electric attacks should be brutal when you're knee deep in water. I'd be shocked if he doesn't have a zonewide AOE like Jin Dahaad that requires you to hang on wedge beetle to avoid being electrocuted in the water. THAT would be a great into back into the series.

There needs to be a Master Rank, with bigger hitboxes on their attacks, more wind and tremor effects, and double the hit points. I don't understand how I'm practically sitting in their crotch while these massive beasts do spinning backflips and I don't even feel a gust of wind, something I used to actually consider when building armor. I get that this may be a more accessible game, but at least give us some serious challenge as an option in the endgame... Make it feel like I'm toppling a massive beast, not just bullying a helpless animal back into extinction.
