Reanimator Styled Queen Marchesa. Use her card advantage and the graveyards around you to raise the perfect empire!

Breakdown:

Your goal is to stall and control the board until you have enough mana and bodies in graveyards to start mass necromantic spells. You can chain certain creature reanimation spells and tutors together to grow both your board and graveyard.

Combos:

Sidisi, Undead Vizier + Ever After: Fairly simple, let Sidisi exploit herself and tutor Ever After and repeat. Each time you can resurrect an extra creature for value.

Solitary Confinement + Monarch: Though this also works with any form of card advantage, getting Monarch through Marchesa is the most reliable. After this you can't lose Monarch outside of other ETB Monarch effects. With this barrier up you should have time to build up a boardstate or reanimate one.
