Shroud on a giant flier is a different proposition than shroud on a small creature: there is nothing to protect by trick, only a finisher to insulate from removal. That is the design logic at work in this Leviathan. The body is a clean evasive clock, flying and trample together meaning chump-blocking buys almost nothing, and the shroud means the answers an opponent most wants to draw (single-target removal, the bounce spell) simply do not connect. What you are left with against it is the set of effects that ignore targeting entirely: a board wipe, a sweeper, a Wrath, an edict that makes you sacrifice. That narrowing is the pitch. The trade-off is paid in the cost itself, expensive enough that this was never a tempo play; it arrives as a top-end haymaker meant to end the game in a few unanswerable swings. The combination of evasion and untouchability has aged into a recognizable archetype role: the ramp payoff that does not fold to spot removal, the thing you cast when you have the mana and want a threat that shrugs off anything that has to target it. Where blue-green ramp wants a finisher immune to the interaction those colors otherwise struggle against, this Leviathan was among the early clean templates for the job, a shape later designs would refine but rarely improve on.
