Lottery is sepparated from magic competition, however there is magical security preventing silent image or even prestigitation level shehanigans with the tickets. Each ticket has number and arcane mark unique to given ticket. However it's reasonable that Dask wants alluran to sate the angel while Dask sleeps and asking around city she learns alluran was brought and sold to local merchant lord who deals with gambling, there was no special prize listed in lottery (which has been active long while) until after noon so Dask can connect the dots together (and can find out said merchant lord hired a adventurer to guard someone as well).<br/><br/>So Dask buys ticket but already plans ahead as winning chances are unlikely, so she has angel with divination ready to locate the winner to be in magic competition (and thus unable hear the lottery win announcement) and Dask then steals or swaps the tickets during the match. No intention win overall and just wanting alluran which is on lottery (albeit this creates irony on itself that there is alluran as winning prize in magic competition as well, it's just that Asgardians kept secret better than slave dealers :P).<br/><br/>Anyways in short I approve the plan Kunoichi.
