In descending order, Id rank these cards for ninja decks and strategies like this: #5
On its own, it gives you and your permanents hexproof until end of turn, which is already solid
Heres how Id rate the 10 to start: Tier 1 Archetypes (best decks) UR Big Spells BG Graveyard/Midrange Tier 2 Archetypes (good) Tier 3 Archetypes (decent) UB Control/Good Stuff GW Go Wide/Midrange BR Wizards/Bleeder RG Landfall/Stompy The main delineation between these archetypes is the level of synergy and support they have
Turning a late-game land into a creature is useful, and I like that you still get the land from exile if you cast the adventure first, which is something you dont get from MDFCs
The deck also features SOLDIER // Rebel tokens, ready to join the fight
Its second ability makes a great mana dump in the latter half of EDH games: The conditional modified attacker stipulation is easy enough to satisfy, so 5 mana for a 5/5 flier is a great price
