Produce a total of 8 tokens, including saprolings or octopi, to meet the objectives. Keep some removal and creatures in reserve, since the AI can clear the board with either Slaughter the Strong, or Settle the Wreckage.
Build towards Teferi's ult, using Legion's Landing with Queen's Commission to generate more vampires and white mana. Summon 8 vampires (including tokens) and 3 big creatures (Blood Baron or Etrata) to meet all objectives.
Beware of the Gateway's ult, which will kill you if the AI has the City's Blessing. Win quickly, and cast 4 creatures to achieve all objectives. Prioritise getting a Sunbird in play, then casting spells. Try to avoid Cyclops in the first creature slot, as its power can be set to 0 by the AI's Thaumatic Compass/Spires of Orazca.
Due to a bug, the AI's Willbreaker can freeze the game when triggered. So have Sunwing in play and kill Willbreaker as soon as it's played. Slow the AI down by playing Teferi's alt, then casting BSZ for maximum draw to make the AI's cards more expensive. Try to have removal in both spell and support form ready and charged in hand, to be ready to deal with Willbreaker at any time. Play four cheap supports (Storm, Mox, or Binding) and at least 8 tokens from March or Spy Network to meet all objectives.
