It would have been a great pull to get another higher-than-rare pull
If multiple removal-heavy decks like Jund, Mardu Pyromancer, and Jeskai Control find homes in this brave new Modern world, I could see this cards stock going up considerably
and how long they would take to do it
In our example Play Booster, two of the best threats are Relentless X-ATM092 and Gix, Yawgmoth Praetor as "The Shadow Lord." Relentless X-ATM092 is a high-power creature that forces your opponent to block or take damage, while "The Shadow Lord" draws cards over the course of the game
Efficiency can be determined simply by the reward you receive at certain mana costs (Counterspell and Cancel do the same thing, but Counterspell costs less), the total payoff you receive from a single card (Hull Breach and Decimate are both good cards, but Decimate usually covers much more ground), or the payoff you receive in conjunction with other cards (Anointed Procession makes other token production cards completely absurd if unchecked, which is usually better than adding one more card that simply makes tokens like Spectral Procession in a token strategy)
