Esper Superfriends

Tamiyo is good and I wouldn't mind fitting her in if I could but I'm trying not to overload on the high mana cost cards and I wouldn't know what to pull out for her and I really like the synergies of the walkers I currently have so I don't want to lose any of those.

Knight-Errant might be better but since she is fairly expensive and not in standard so I have not chance of pulling her in a pack, my chances of getting her are low.

Isn't knight errant cheaper as of now?

Also... do not underestimate Ashiok

Knight-Errant is a little cheaper I think but its still a little out of my price range. After thinking about it more I think even though Knight-Errant may be a little better in most cases, because this is more of a control deck without much token pump Sun's Champion might actually be slightly better here anyway. Idk, if I manage to find a couple Knight-Errants for cheap I may get them and give her a try.

I really like the look of Ashiok my only concern is what to pull out...I'm not sure if I'd be ok pulling a few control spells for Ashiok or not.

Also I'm sorry to say but control should have 25 lands MINIMUM, take a look at my standard deck

Also, if this is for modern I recommend, Path to Exile, Remand, or Venser Shaper savant (Think of him with his planeswalker)

I would cut Think twice for remand, grim affliction for path to exile, celestial flare for wrath of god.

I don't mean to sound like a dick but... this deck wouldn't do so well in Modern. I thought I had a pretty good deck, it really was a good Sword of (blank) and (blank) deck. I did not win once. The decks are too fast and expensive in modern. I recommend Standard, after I lost by a horrible landslide my first tournament I went to standard.

Pretty much you have to stop:

Tarmagoyf (Ashiok or scavenging ooze are good)
Dark Confidant
Tron decks
Flash Control decks.

It's too expensive of a format and it's not very fun...

Standard is fairly cheap and pretty fun

Here's a pretty good modern deck:

First off, just to be clear this is a Modern legal deck but it is not meant to be tournament quality. It is just a fun casual deck I built to play with my friends. You are right the format can be expensive, and I don't have the money to compete against the Tarmagoyfs and the Trons, etc. in competitive Modern.

Path to Exile, Remand, Venser Shaper Savant, Wrath of God are all good cards and might make my deck better but I don't currently have access to those cards.

I play a lot of control (mostly U/W or Bant) so I'm very familiar with the usual 25-27 lands in control decks, this is just a starting point in a casual/fun deck and may very well add in a couple more land if I find cards I want to cut as I playtest it further.

Some of my card choices in the decklist may have 'better' options but were used instead because of personal playstyle preference.

Thank you for the ideas though, if I wanted to make this a competitive deck in Modern I would want to make a lot of the changes you suggested.

Oh sorry, I assumed it was competitive because of the championship coming up :p

I fully realize Thoughtsieize is the preferred and popular card for that type of effect but seeing how it is a lot more expensive and i don't currently have any I am choosing to stick with Duress for now. If I get lucky enough to pull a few of them from Theros packs I will replace Duress.

Thanks for the input.
