I'll start by saying please playtest this deck for a few weeks before you comment on how TfK works, or how meditate works.
Yes, it may draw you into a piece you need, however the likelihood of that being countered against control, and then giving them a free turn is too high.
This simply doesn't make sense. First, if this card is countered, then you do not skip your next turn. The 'skip your next turn' crap is part of the effect, not the activation cost

Second, if you are playing against control, and you play meditate at the right time (yes, magic does take some skill and you do have to know how to play certain cards in certain decks), isn't it a good thing for the opponent to be wasting his counters on this?? If it is a guarenteed 3cc, instant speed FoW/Mana Drain grabber, then why not play it? USUALLY, this is how it goes (I know from playtesting, not because I am pretending to know

):
end of monoU players turn/control players turn:
me: tap 3 mana, meditate?
1) Good opp: *looks at board...1 smokestack 2 counters* "Crap...FoW it (if no 3sphere/mana drain)...*
2) Bad opp: *looks at board..reads card* "Oh..so, you skip
your next turn? Hmm, that seems cool...okay it's fine."
choice 1) i bait out 1/2 cards, and have cleared the way for a threat (welder, ancestrallllllllllllllllll, anything, draw 7 if you need it even).
choice 2) you just won the game. you'd be suprised how OFTEN this happens when you play against people who don't know how to play against stax/meditate.
So, obvious shit aside (meaning yes you will have to know how to play in order to use this card), meditate is amazing in stax.
As for 8 draw cards; stax doesn't have enough room (atleast mine doesn't) for 4 TfK and 4 meditate. It also depends if you are running draw7s or not. I believe in wheel and jar only. Timetwister often ruins me or is a dead card, and windfall just doesn't restock my hand as nicely. Again, I play balance and yawgWIN in my build, so yawgWIN is basically a draw 7-x, where x is bigger allllllllll the time (further into game, the better) which is unlike many draw 7s (usually stax goes: dump hand, i need food....draw7?).
To each his own, but I suggest playtesting before telling people to run TfK or whatever, and how meditate is sub-par. Meditate is broken.
