I have two suggestions : First off "Mass Manipulation" with X=1 costs UUUUXX and takes control of X target creatures/planeswalkers with some small stuff like "Healer's Hawk" for W. Basically no matter what that striped woman is, she should be ours now and if not we have a little chumpy blocker to protect us and give us back some health, something we are in dire need of.
Second: "Luminous Bonds" for 2W on the woman, it should disable her, it prevents a target creature from attacking or blocking. If not, we still have the mana for four smallish creatures (1 "Pteramander", 1 "Benthic Biomancer", 1 "Peltcollector", 1 "Healer's Hawk" f.e.) tap their energy to cast "Conclave Tribunal" for 3W and exile target nonland permanent.
Both plans leave us with some forces assembled to protect our Planeswalker and should work on anything we have encountered to date. The second one is safer, just start with some creatures for the Tribunal, fish for the countermagic we are familiar with and if it comes, it's wasted, if it doesn't we have the situation under control.
[X] [Plan] The Safe Route
- Cast "Pteramander" for U
- Cast "Biomancer" for U
- Cast "Portcullis Vines" for G
- Cast "Healer's Hawk" for W
- Cast "Luminous Bonds" for 2W
- Cast "Conclave Tribunal" tapping the creatures for 3W
Obviously this works only if we can actually cast multiple spells simultaneously, but even if we are "running Singleton".
If we can't do that Mass Manipulation
