Reminds me of how fun that one battle was. You spent ages trying to get the bugger and then it faced you. The sad thing is if you beat it or let it simply leave then you could not get Ho-oh as you needed Suicune to go up the tower.
The synth is quite amazing in this one and I like how manage to capture the original spirit of the battle as it made you gasp every time it got out of the ball. I could never get Raikou for some strange reason. The drums sound epic here and so does the chorus. Amazing work on this.
Overall, greatly epic remix of a cool song.
