Ways to get multiple Kel'Thuzad

I thought it would be fun to make a deck based around getting multiple Kel'Thuzad(s) (what's the plural of Kel'Thuzad?) onto the board. At my pretty low rank (15) that seems to be an unbeatable situation except vs Priest with Mass Dispel.

What are all the ways to get multiple KT? I normally use Faceless Manipulator, but that can't be played on the same turn as KT. I think I've seen cards such as "deathrattle: resummon this minion" and "destroy this minion and return it to life with full health" that I think could work, but I don't have them. I could craft them though since I recently dusted Lorewalker Cho.

Ideally, I'd be able to incorporate them into one of my existing anti-aggro decks since this strategy is kind of moot if mech mage / hunter with way too many snakes kills me by turn 6.

UPDATE: In case anyone was interested in how this turned out

Solution 1:

All possibilities of getting additional Kel'thuzads in addition to the one that can be put into the deck normally:

1. Faceless Manipulator
2. Sneed's Old Shredder (1/62 chance of KT)
3. Recombobulator on an 8-Drop minion (1/10 chance of KT)
4. Echo of Medivh
5. Unstable Portal (Incredibly low, but non-zero chance of KT)
6. Duplicate
7. Reincarnate (New KT resummons old KT at end of turn.)
8. Ancestral Spirit (New KT resummons old KT at end of turn.)
9. Redemption (New KT resummons old KT at end of turn.)
10. Resurrect KT on the same turn he died (New KT resummons old KT at end of turn)

In addition to the above methods controllable by your own deck, mind control effects can steal your opponent's KT if they happen to be running one.

Solution 2:

• Faceless Manipulator
• Echo of Medivh
• Reincarnate (resummons a second KT after the end of your turn)
• Ancestral Spirit together with Reincarnate (and optionally Baron Rivendare)

The Shaman spell Reincarnate is probably the most useful of these as it costs only 2 mana and could be played on the same turn.
