i play with kiki and it is really awesome!!
you can copy a matron for searching any card like incinerator, it can copy a siege gang or a ringleader, or.....

sorry for my english, it's not that good, i'm from germany.
i've found a deck, that uses the mask in a deck like suicide, with several handdestr., also chains are playable, i think.
it was something like this:

3x Phyrexian Negator
3x Nantuko Shade
4x Dark Ritual
4x Duress
4x Hymn to Tourach
1x Demonic Consultation
1x Demonic tutor
1x Vampiric Tutor
1x Yawgmoth's Will
2x Stifle
4x Brainstorm
1x Time Walk
1x Ancestral Recall
4x Illusionary Mask
4x Phyrexian Dreadnought
1x Mox Jet
1x Mox Sapphire
1x Strip Mine
4x Wasteland
4x Polluted Delta
4x Underground Sea
7x Swamp

i think for the sb is back to basics also a good  card.
would you think that this deck (perhaps with some meta changes or updates) is viable in today's vintage?
