Card Ladder is excellent for tracking trends over time
See if you can't figure out how many mana total, and which specific kinds, it takes to summon the following card: The Answer: The first card, (Sylvan Bounty), costs 5 generic manamana of any kind you want along with one green manamana produced by a forest, for a total of six mana
Besides that, its triggered effect to destroy nonbasic lands is expensive (sucking up four energy counters), and it really doesnt hurt an opponent much
You activate Teferi Akosa's last ability without choosing a target or tapping any creatures
So lets improve on what works by culling the other themes out of the deck
If any of its abilities trigger while you cast that spell, those abilities will trigger but won't resolve until after the target has died
