Let's see what the rough ratios are for Feline Ferocity and how it compares: 52 mana: 37 lands plus Oreskos Explorer, Cultivate, Nissa's Pilgrimage, Sol Ring, Sword of the Animist, Hedron Archive, Herald's Horn, Dreamstone Hedron, Mirari's Wake, Zendikar Resurgent, Traverse the Outlands, Blighted Woodland, Krosan Verge, Myriad Landscape, and Hammer of Nazahn (I think it counts) -- I guess you can count Temple of the False God and Saltcrusted Steppe too but I'm not 10 "card advantage": Harmonize, Hunter's Prowess, Soul's Majesty, Skullclamp, Staff of Nin, Heirloom Blade, Kindred Summons, Zendikar Resurgent, Alms Collector, Herald's Horn (kinda) -- I don't count Hedron Archive or Dreamstone Hedron 10 targeted removal: Leonin Relic-Warder, Qasali Pridemage, Condemn, Crushing Vines, Wing Shards, Relic Crush, Argentum Armor, Stalking Leonin, Qasali Slingers, and kinda Grappling Hook 2 board wipes: Divine Reckoning and Rout 0 recursion 2 somewhat flexible tutors: Taj-Nar Swordsmith and Nazahn, Revered Bladesmith 0 graveyard hate 1 what I'd consider a surprise "I Win" card, Kindred Summons, and maybe a huge White Sun's Zenith, but otherwise nothing too surprising Obviously these ratios are a simplification and subject to opinion, but it's still a good way to quickly identify potential problems
