This card may be one of best thwart event in the game. As infiltration costs 1 resource + 1 for the copy of infiltration. you are spending 2 cards to get up to 5 thwart and a minion. Minion tutoring is really powerful with a lot of heroes (Thor, Winter Soldier, Silk, and quite a few other heroes) Unless you have no way to deal with the minion or the scenario minions are way too beefy (Sinister 6) This card really has no downside other then the idea of discard up to 5 cards from the encounter deck which could give an acceleration token faster then usual.
