True. Except in Chaos Mode generally there is the opportunity cost of not getting to cast a spell.
in a game where your number of turns is greater than the number of spells in your hand you are at some point in the match only delaying the casting of a spell. You don't cast a spell on 'that' particular turn, but you do have the chance to cast the same spell on later turns, and the spell will potentially have a greater chance of casting on those later turns because you've been soaking up mana from disbelieves.
Say you wish to cast a Spider, it's at a base chance is 60%, and you can also see that your opponents have 5 creatures left on the map which are potentially illusions. Well if you cast disbelieve, first (and before they do) then the following turn you can boost that spider to 64%, the turn after 68%, the turn after that 72%, then 76%, finally 80%. Delaying the spider cast in order to cast disbelieves first is being incentivised due to that 4 mana given to disbelieve.
This is regardless of whether or not you actually remove an illusion from the map.
And if an opponent decides that they're going to take the same strategy, what you've then got is a disbelieve race where the entire illusion and disbelieve mechanic is being sidelined.

You're getting mana for spell failure with disbelieve. It's a 100% cast.
