Ankylosaurus a bit costly creature, but intesting. We’ll see if that’s the actual name, but the text as translated on MythicSpoilers is as follows:

“Ankylosaurus”
5W
Creature – Dinosaur
Enrage – Whenever Ankylosaurus is dealt damage, put a +1/+1 counter on each other creature you control.
3/5

The interesting thing here is the combo with [scryfall]Walking Ballista[/scryfall].

Of course, with two Ballistas, you can go pretty infinite (except that Ankylosaurus will of course die at some point), but how about just producing a horde of tokens and making them big?

[deck]
[creatures]
4 Anointer Priest
4 Ankylosaurus
4 Walking Ballista
4 Adorned Pouncer
4 Kinjalli’s Sunwing
4 Angel of Invention
[/creatures]
[spells]
4 Sram’s Expertise
4 Oketra’s Monument
2 Cast Out
[/spells]
[lands]
4 Desert of the True
4 Shefet Dunes
18 Plains
[/lands]
[/deck]

Could we fit [scryfall]Crested Sunmare[/scryfall] in there somehow? The curve is pretty problematic right now. Maybe work in [scryfall]Servo Exhibition[/scryfall]? That would definitely help, but would also make the Monument worse. There’s a lot of balancing that would have to go on in here, but there might be some seed of something interesting here.
