* [SLD] Implement Captain America, First Avenger
I made assumptions that WotC is going to fix the rules by adding "choose the equipment you're unattaching with Throw..." to rule 601.2b so that this card actually functions since you have to choose a TargetAnyTargetAmount in steps 601.2c/601.2d long before you actually pay the unattach cost in 601.2h.
* Remove Target workaround, add proper 601.2b handling for choosing cost targets early using inheritance to avoid having a horrific brittle list of 'these costs must be paid early'.
* Fix HideawayPlayEffect to allow you to attempt to play everything, in cases of multiple Hideaway triggers.
* Allow users to choose order of cards to be potentially played.
* Update HideawayPlay and Arcane Bombardment to not ask if you want to play the cards you chose.
Update tests, add tests for
- Select the order in which to play cards
- Attempt to play two lands with only one land drop available, only the first land enters play
- Play two lands with extra land drops available.
* Fix no-parameter constructor.
