Siona's Budget Combos (EDH / Commander) [Revision 5]

Casual, budget-friendly combo deck. There is a better than 50% chance of having all of the cards for some combo on turn 5. The original loops are the Famished Paladin group loops: 3 card combos based on a creature with a built-in untap mechanic and tapping that creature to ping damage, create a creature token, or gain life. Famished Paladin and Lurking Roper need lifegain to untap. Barrenton Medic and Devoted Druid need Vizier of Remedies to untap by replacing the -1/-1 counter payment.

The second main set of loops are the Scurry Oak combos. The basic version is a 2 card combo: Scurry Oak or Herd Baloth with Cathars' Crusade or Ivy Lane Denizen. Generates infinite tokens and makes Scurry Oak/Herd Baloth infinitely large. The 3 card version breaks the Cathars' Crusade effect into two parts: the creature token triggers life gain through a Soul Warden effect, then the life gain triggers a +1/+1 counter through a Sunbond effect.

Miscellaneous Combo Pieces: Midnight Guard goes with Presence of Gond to create infinite tokens (the two card version of the main loop). Shielded by Faith goes with Siona, Captain of the Pyleas for the commander combo to generate infinite tokens. Stuffy Doll enchanted by Pariah will prevent you from taking any damage until one of them is removed (note: if you choose yourself as the player for Stuffy Doll's first ability when it enters the battlefield, enchanting Stuffy Doll with Pariah will result in a draw the first time you or Stuffy Doll takes damage because that damage can no longer resolve). Stuffy Doll enchanted by Guilty Conscience will let you deal infinite damage to the chosen player.

The remaining cards are budget-friendly ramp, Fog effects for fun combat tricks and to buy time to find combos, and enough removal to contribute to stopping faster decks. Sun Titan will can recover most of the combo pieces from the graveyard if they've been removed, and Boonweaver Giant can search for or recover many of them as well.

Possible upgrades: swap some of the "Card Advantage" cards for actual tutors: Yisan, the Wanderer Bard, Sterling Grove, Eladamri's Call, Congregation at Dawn, and Idyllic Tutor would be good upgrades. More interaction (especially creature spot removal) and some stax effects could also help: Gaddock Teeg and graveyard hate would be good places to start for stax effects.
