WOW, is the first thing that poped into my head when i saw it!!! Sonic Blade peaked my interest because it's great ability to take a huge chunk out of your opponents pokemon, Dropping any pokemon to 50 hp leaves them open to even a smaller attack, making even smaller pokemon have a bigger impact, then i saw "Psychic Cut" OMG!!! They just made this good card great, it can do 60 damage witch if you used his Sonic Blade attack first will knock out the defending pokemon (unless they healed it). But even if they do, just reveal battle rewards until you have enough to finish it off. Or just go for the Psychic Cut and flip 1 or 2 battle rewards and knock out there pokemon, then take one of the ones you flipped earlier. It can easily sweep there hole field in a matter of turns.
I use it on it's own or maybe with an Expert Belt equipped, and just go straight in to battle with it. Its ability to do 80 or 100 every turn if you have expert belt, just by revealing 1 battle reward, witch you will just take when you knock out there pokemon (witch you more than likely will). Or if they just played there big 140 to 160 hp pokemon if it can live through two attacks from that pokemon, just do Sonic Blade the next turn (if its not knocked out) use Psychic Cut then there O-SO big pokemon is gone. Or if you don't even want to give them a chance to attack Gallade, attack with it's Psychic Cut, and flip enough battle rewards to knock it out.
(Strategies and game play)
As i said above just bring it out if they don't have any big pokemon and knock one out each turn or wait for there big pokemon to come out and attack it with Psychic Cut, and just reveal enough battle rewards to kill it.
(Combos with other cards)
The nice thing is that this card is very self reliable and can deal with all kind of situations, with several small pokemon or even 1 or 2 big ones, if you play it right its totally self reliable. But Expert Belt is all ways nice, giving him a little more hp and doing 20 more damage can be a big help. And I like running Cyclone energy to bring out there big pokemon while there trying to put more energies on it, and take it out before it can do much harm.
(Ways to counteract it)
The only reason this card is not totally broken is because it's main attack slowly dwindles itself to a simple 3 energy 60 damage attack, so in a way it counteracts itself. But even thats not too bad, and if it comes down to you using his Psychic Cut attack so much that all of your battle rewards are face up, you MORE than likely have knocked out so many important pokemon that its to late for them to make come back. But you can also counteract it with a big hitting psychic pokemon witch could knock it out as it has +30 damage when hit by a psychic type.
-Big hitter (Damage Wise).
-Can take out multiple pokemon easily.
-Can take out big pokemon easily.
-Takes a while to get out (Ralts and Kirlia are the earlier forms.)
-Has a weakness.
-Its best attack slowly gets weaker but stays at a solid 60 damage in the end.
It came in two sets POP 7 (My personal favorite) and D&PSW each with it's own art.
(Artwork and aesthetics)
The art work is amazing in the POP 7, It depicts him showing of his blade skills, and the other art shows his speedy side.
Over all i give it a 10 out of 10. Its perfect, not to broken, not bad in any way its just all around amazing. Boarding on GREAT and BROKE XD LOL.
