All your modified creatures get trample, and dealing damage with a modified creature lets you thin your deck out a bit by searching for a basic land and putting it into play tapped
its the ability to fetch up any land at any time that makes this interesting
Even something like Makeshift Binding makes for a decent removal spell, even if you could realistically swap it for something better like an Oblivion Ring, I left it here for the fun of keeping it close to the original deck
Compatibility with improvisation is also good as it allows you to draw events with powerful effects, such as Fluke (3), Twist of Fate (3), and, look at this, Will to Survive (3), once per turn in exchange for discarding a card from your hand
the (if any) clause means that even if Invader is the only card in hand, you must still activate the effect and then special summon it without any discard
