Here are the monsters you can discard with Cards of Consonance to draw 2 cards. The White Stone of Legend is a good target because when he is sent to the graveyard you get to search out Blue-Eyes White Dragon, making this combo a +1 in card advantage.
All, exept for the Synchro monsters, Dragon-type Dragunity monsters are Tuners with weak stats. Most of them you can use as cost for Cards of Consonance. Additionally they want to be in the graveyard to be equipped by the Winged-Beast Dragunity monsters on your field.
updating this page: add the new water dragon tuner from the new blackrose dragon pack.
This could potentially be a big card for water decks. Finally some much needed draw power. A new water tuner monster never hurts. Water decks are very powerful mid-late game but usually struggle early game b/c they really need their combo pieces to shine. Well that draw power maybe just what they need to give them a fighting chance against neos, red eyes etc
ps: water neos is actually really good... try it. Especially with jaden's neo space skill and aqua neos w/ atlantean engine.
