With these cards (and any I may have missed), part of the ability on each spell says “boot this (dude/huckster/blessed).” If the spell pull fails, does the dude still boot? I want to say no, as the entire ability fails. But booting is also part of the cost, so I’m therefore not sure.
The Dudes do not boot as part of the cost
Edit: the card boots, not the dude
Abilities
Abilities are card-text indicated by boldface text detailing the timing for activating the ability (e.g. Noon, Shootout, React) and any costs (e.g. booting), followed by a colon. The first sentence after the colon is called the “Requirement Clause,” and must be satisfied for the ability to be able to be used. There is one exception to this: if a Requirement Clause begins with “If,” then the requirement clause is allowed to fail, and the ability can still be taken. When this happens, continue with the ability and resolve the additional clauses. All other clauses after the first sentence must be met.
