mtg steve card Custom Metal – Personalized Magic Card Design on Brushed Aluminum – Create Your Own Unique Collectible Gift (Creature) : Toys & Games MTGNexus - Steve, Worldly Traveler

Each pack has a theme, whether thats adding counters to creatures, every creature being a cat or being centred around a powerful planeswalker

Gemstone Mine is unique in that it has a limited number of taps due to relying on mining counters that reduce every time it is tapped, it enters with three counters and gives one mana of any color when tapped

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)

Is Reap the Past better than the other options

If multiple instances of the ability are on the stack (perhaps because multiple enchantments entered the battlefield under your control at the same time), you will be able to create a token copy of an enchantment for only one of those instances
