Back again with another MTG post. Went to one of the card stores a few hours back, hoping to look for copies of Doomed Traveler, but instead found this interesting common just waiting to be used.
First thing that came to mind was to use it in my Blue Illusion deck. While this isn't an illusion, it's an excellent 1 mana drop that turns into a good flyer as early as turn 2. Now, that's not something to take lightly. Another good thing I realized is that it remains a human, even after transforming. So I can experiment with the Innistrad equipments for humans, especially since Lord of the Unreal is also a human.
Now, while Delver of Secrets may be tricky in it's transformation, there are ways to make it so that you know it will surely transform. For example, a card like Ponder will have you look at your deck and make sure there's either an instant or sorcery so it transforms. Another way of helping out is by making sure your creature count is a bit lower than other spells. But the best way is using cards like Ponder or other abilities like Scry, for example.
Perhaps there's a way to abuse this and Invisible Stalker for a very aggro Blue Human deck. That would be pretty fun, but for now I'm just going to use this with my illusions.
