I know these numbers are subject to change, so this is purely wishful speculation. Takeda could theoretically have something similar to Rune Trap with his MB Kunai. As of right now they are + enough on block to allow him to execute any of his pressure options. They also deal almost 5% on chip, or a full combo on hit. They hit low and can be delayed in conjunction with his overhead to lead to an Earthshake-level overhead-low trap that can be reversed to a low-overhead trap based on timing and that leads into full combo on hit. So even if you somehow managed to block every single one of his mixups, you'd still be eating between 15%-20% chip damage (including the chip from his normals) for 3 bars of meter.
I'm also curious what happens if he throws down the kunai, delays them, and then goes for a throw. Will the explosion whiff or will it knock the opponent out of the throw? I'm guessing whiff.
