Ask yourself whether you can double dip on it and if not, then its maybe time to skip it for this build
That's great on its own, but Gyome also lets us pay to sac a Food token and grant a creature indestructible for the turn (at an additional cost of tapping it, like the way the troll mechanic Regenerate used to work!)
I really like the card art for Metamorphosis here, which just looks painful as the man is transformed into a snake
When this creature enters, create X 1/1 red Phyrexian Goblin creature tokens with haste, where X is the number of creatures you control
This is typically done with an [c]Entomb[/c] + [c]Reanimate[/c] combo, putting Griselbrand into your graveyard and then reanimating it
The ability to ink the card makes it hard for it to ever become dead weight, making it a strong option to include in any Steel deck
