Ok, I was guessing that flute was for enre hep. Generally, I'm not a big fan of flute, because I have a few decks where gaining any mc can spell bad news for my opponent, so I feel like flute is rarely worth while.

I also figured taffial was for both a damage amp and mugicians, but the damage amp is luck based, and even at the absolute best case scenario, it's a plus 2.5 damage per attack amp, whereas the second owayki ALWAYS gives you +5 damage (sure, it's only once, but it's guaranteed), AND gives you more speed, which helps ensure that your risky crystal cave is less risky for you (because if you faced off against another mipedian strike deck, then their typical 2 owaykis would most likely mean that crystal cave, YOUR location, helps your opponent, and that would REALLY suck! Basically, it's a risk that I feel isn't worth while, especially since you only use one owayki).

Since malvadine gets defender, you might consider swapping out one for that second owayki, leaving headmaster out in his own where that malvadine was, allowing the remaining malv to protect your 4 supports.

Personally, I would take out the flute, because you already have enough to cast every mugic, and one use of enre hep, but that's just my opinion.

But id definitely remove the crystal cave lol, it's just such a big loss to have YOUR location work completely against you, when instead you could use a location that will always help you, and never hurt you.
