Delney, streetwise lookouts second ability will ALWAYS trigger any abilities given to Thunderbond Vanguard, regardless of its power.

To replicate, have Delney and Waystones Guidance on the field and cast Thunderbond Vanguard as your first creature spell during the turn. You also need one additional creature on the battlefield so that Thunderbond Vanguards power is 3.

You will find that Delneys first trigger does NOT activate when Thunderbond Vanguard attacks, it can still be blocked by any creature, yet the triggered ability given to it, mobilize, WILL trigger Delney for a second activation.

Thunderbond Vanguard is a cracked and broken card. It does not need this additional help. It should not benefit from cards that affect creatures with power 2 or less when its power is 3 or greater. Please address this.
