https://www.youtube.com/watch?v=YYo1PTW6MfQ&feature=youtu.be Fun using Tree Spell
So I was very impressed by this vid, and seeing how this guy was using this with Anubis in actual dungeons, I was thinking this is totally workable and not just some fancy things that you can only do once in a blue moon.
I only have one magician, the light time one, so I just brought that with me and went testing in the Endless Corridor.
Turns out Light Time Magician might be very suited for this job, because he comes with 2 Time Extends and also delays the opponent a turn, so if you can take a hit from the boss, you have two turns for board arrangement. Finally, he makes hearts so him+HeartBreaker can be splashed into any colour team for 10 combo fun times.
Don't know if any one cares except me but here's sort of a mini-guide to what I did to try to mimic the guy in the vid.

First, we look at the board and start counting orbs. Here, we're turning heart to green and they're our main attack orb, so just focus on the other four colours.
Red - 8 (excess 2)
Blue - 4 (excess 1)
Light - 7 (excess 1)
Dark - 3 (excess 0)
We are trying to make all orbs count a multiple of 3, and we can only turn 6 orbs, so you might realize by now that 10 combos is actually doable in most cases! Only the most unlucky of excess 2,2,2,1 or 2,2,2,2 combination would render you powerless. (But you can at least fix the board to 9 combos, which is still very impressive)
So here, we want to remove 2 red, 1 blue, 1 light. The rest will be hearts or green.
Since my magician is not evolved(no awakens)/these orbs are in the middle and in the way/my puzzling skills not good and fast enough, I've decided to simply devote my first turn to brining these 6 determined colours to the middle row, and try to do a little board arrangement (like moving far away orbs together, or preparing for the bottom row combos.)
Here's the result of my first move after using magician's skill:

Magician's skill will delay enemy by 1 turn, so if this was a boss fight, I'd have another extra turn to arrange orbs before going for the kill!
The next move's aim is to prepare 4-5 easy combos so that it makes 10 combos ultimately easier. There are different techniques for this, but the common one is actually making the combos, then "move through it" to break it apart, then your next turn you can easily move in the reverse direction to recover them.
Result after 2nd move and using GreenValk:

Was holding the blue orb and moving it to the rightmost-bottom, but time ran out. Nevertheless, this is still a very fine board now, one thing to take care of when attempting 10 combos is that the I find that the top most rows are usually the most difficult to deal with when arranging combos like this beforehand. This time, I made use of the fact that there were two dark orbs at the top so I kept them up there and by starting from the top-left Light orb I can easily make a dark combo to start off.

The end. :V
This is the most fun I've had with puzzling since practicing making 3 rows with 18-20 main colour orbs. It still amazes me how PAD continues to evolve and people discover more techniques.
Now I've definitely going to lv up this magician, and try splashing him in my various teams! At first I only saw him as an inferior LMeta, who would've thought he'd turn out to be so fun to use!
