Great deck, I would drop the Echo Mage, he's just asking to be removed, probably just add some more removal in his place.

Dropping Echo Mage is kind of a tough call for me though. Against burn decks, he makes it so that the opponent takes twice as much damage as I do. Same thing with mill or control decks, or spells that put tokens into play or counters on creatures.

And as I said in the description, he's able to make my own spells very efficient too. Bounce three lands and cascade with Deny Reality for just 7 mana. Tap two creatures and untap four lands with a tripled Hidden Strings, or just tap up to six blockers in one shot. Last Gasp a 9/9 or weaker creature to death for four mana, even if it's indistructible or can't be hit with Doomblade. Tripled Treacherous Urge to gain a sudden offense for a turn.

I'll take a look at what might replace him, but it won't be an easy change. If you can think of a card that would work better for this deck than he does, please let me know.

Against burn decks he's far too slow, and if they were worried about him, they could just as easily burn him. Versus mill decks they will have milled you considerably before you can even duplicate their spells. Against control decks, they would love to see you sink your mana for the turn into him, because it means that you didn't play a threat, and when they kill him, they get extreme value. As far as duplicating your own spells, do you really want to pay 5UUUUUU just to get a creature that can UU duplicate? Or would you rather just play a spell in his place.

....Okay, fair enough. And looking at Gatherer, there's a couple fairly obvious choices that would do the same job for less investment - particularly Twincast and Mirror Sheen.

But in any case, you're right. I'll have to experiment and see what I can come up with.

Maybe card:Despise would be a good spell to had to this deck

Cunning Lethemancer might give you an edge, especially against multiple opponent, also Dimir Cutpurse migth help you early game in reducing his hand size and expanding your
