It kind of depends on your power level, right? Cards like this don't necessarily need a ton of synergy to make it into a final 40, but they benefit immensely from drafters who build around the things they're trying to do. A good recent example of something similar to this is Up the Beanstalk: beans doesn't require a lot to be worth putting into a deck, but it gets infinitely better once you start combining it with things like Delve Spells, alternate costs, and Cost Reduction Effects so you can start stacking those triggers more often.
I have a bad feeling we'll start to see this stupid guy everywhere. There's some hint of purported synergies (blink, sacrifice, ninjutsu) but that's like saying Ragavan is good for artifact matters and play from exile themes.
Being a creature, guy is obviously more flexible than Beans, but I think he might still have that "unlock the fun" potential that is still missing in a lot of threats.
