This kind of effect can close out games sometimes, but it also frequently does nothing, and the base stat-line here is kind of rough
Honored Hydra is a big pile of stats and compares to the aforementioned green flashback cards
Don't get too hasty to stop something

The theory is that, as Yedora3 brings back non-token creatures as face down and lands, the ability does not remove the interaction between Morph or disguise and being face down - I can morph in a creature, turn it face up for effect, throw it at the enemy to get it killed, bring it back as a face-down card that is a forest, then flip it face up (again) for its morph cost
Those indestructible lands that are also artifacts look even better now
