Relatively early on, I ate a 20-damage swing facilitated by a combo from Demolisher Spawn and Ursine Monstrosity
You're already aiming for a mana advantage by hitting a higher-cost artifact, but Mutation throws in a small army of creatures too
But it was absolutely the right decision theres no way you could have taken Space Marine and Tyranid cards seriously if they were sitting next to Llanowar Elves
Seriously, the reason why Teferi and Narset have been the two most impactful planeswalkers in War of the Spark has as much to do with their mana cost as anything else
Some Supporter cards, like Koga, can effectively counter Asleep by facilitating a Retreat, thus waking the affected Pokmon
If you thought Smaugs 14 Treasure tokens were ridiculous, just wait till you swing in with this monstrosity and spill 20 of the things out onto the table
