The evasion clause is doing the load-bearing work here: unblockable by anything with power 3 or greater means the biggest defenders on the board simply cannot interpose, while small chump blockers stay in play to absorb everyone else. That is a narrower, sharper cut than plain menace or flat unblockable, and it rewards a build that commits to the offense rather than one that sits back. The surveil trigger reframes what the wider board is for: it scales off tapped Assassins, so a crew that has already attacked and tapped down isn't just spent damage, it's a graveyard-filling, draw-smoothing engine on the end step. The interplay is the whole point. You want Assassins swinging (which taps them), which sizes the surveil at your end step, which sculpts the next few turns of the assault. It ties the tribal payoff to combat rather than to a static creature count, so an idle Assassin held back on defense feeds nothing; only the ones sent in pay off. And the 3/2 frame keeps the leader honest as a threat that dies to nearly any removal and trades down in combat despite the evasion, so the value engine is priced against a genuinely fragile body: connect and you snowball, but you rarely get to connect for free.
