Well I think we might need to call a judge to forfeit this match, Spiderman, because I think we are about to disagree about reality.
"In that case they are relying on one card to see them through their matches. Why can`t good players beat bad players without the Disk?"
They do, but they cannot be as reliable. The good players will always float to the top in any environment, but their consistency in doing so has dropped since Disk left. No matter the field or environment you would expect the good players to outperform the bad, but the matchups/luck index has risen since Disk left.
A good player used to relish meeting a bad player, he used to relish the sight of his opponent throwing out his cards in a mad rush because he knew the Disk would arrive and win the game for him there and then. Now the matchup against bad players can be scary because you have no sure way of dealing with their cards - bad play is positively rewarded in the new Type2 because the chances are not only will you avoid losing to Disk if you empty out early, but you will catch some players with a mana screw and win games you might have lost by playing technically correctly.
Example:
Opposition is THE WORST card. Okay, it`s an enchantment that does nothing by itself, and in fact requires you to have a mass of creatures in play to use it. But in the new Type2 not only is it good, but it rewards playing without token generators (the only acceptable way of playing Opposition when Disk is around would be with a rapid generator) as they are vulnerable to Powder Keg.
"Control started to wane about Tempest"
Hmm, that would be because it didn`t get any good spells like Whispers, Forbid, Tradewind, Capsize, Phoenix, Survival, Weaver, Legacy`s, Oath, or Edict?
I`m afraid I have to disagree on a basic level.
I think the major sea change came much earlier, it was the printing of Fireblast in Visions which first kickstarted beatdown decks into the first Tier when Magic had preivously been ALL about control matches.
But control was always the number one deck (Ophibounce, Forbiddian, 5cU, Draw-Go Oath, Counterphoenix, Draw-Go again, WillNecro) right up until the Disk went in 6th. From that point it has been impossible to build a truly consistent control deck.
The control decks have had to accelerate their attack window by around 10-20 turns and are now largely dependent on Masticore as both defence and kill. This means they cannot possibly be as solid because Masticore is nowhere near as solid as Disk when it comes to removal and defence. Control is the most skillful decktype to play, it requries thought and planning and is basically the hardest type to play, but if control is unreliable compared to other decktypes then good players are forced to throw themselves on the mercy of playing beatdown and topdecking in tight mirrormatches, or try to get lucky with control decks and actually use their playing ability if the cards fall right for them.
"WOTC tried to slow the field down with US and MM, I guess they didn`t go far enough for you"
Well I don`t think this is really an essential part of my point - I would never complain about rotation as I see it as a player`s job to keep up and evolve. I don`t think I have ever complained about a rotation or banning before, but the loss of Disk has had such a harmful effect on the viability and popularity of Type2 that I cannot avoid commenting.
For your information I don`t generally play control decks, the loss of Disk has not personally hurt me very much. But I do appreciate very fully how much Type2 is suffering as a format in the Disk`s absence.
