No, this deck won't work at all against platinum. The reason is that many platinum decks are too large. However, even the 35x2 card minimum ones will be too large. You won't be able to use as many precogs or sundials to find the stall cards you need, and more crucially, your shards of bravery will deplete your own deck faster than the platinum deck due to its doubled size. (it might take a minute to realize why, but basically it comes down to the shard of bravery being two turns of drawing for the human but only one turn for the platinum deck) You could make the deck larger to combat this, but then you'll either dilute your stall cards too much, and a gap in the defenses will open, or the deck will simply morph into something else with too many additions. (not necessarily a bad thing, it's just no longer 'the blarp' in that case)
