Target creature gets +1/+0 until end of turn. When that creature dies this turn, create a 3/2 colorless Eldrazi Horror creature token.
If the targeted creature doesnâ€™t die this turn, the delayed triggered ability simply wonâ€™t trigger.
If the targeted creature dies before Otherworldly Outburst resolves, the spell doesnâ€™t resolve. You wonâ€™t get an Eldrazi Horror token.
