What Are The Foundations Commander Decks
This one lets you cast Dollmakers Shop early to start churning out tokens and then unlock Porcelain Gallery later on to pump up your entire team and swing for big damage
Perhaps you can see where this is going
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)
Make sure to carry playable cards with you Not carry playable cards, makes it hard to care about your trades I highly recommend grouping cards by color first then synergies ie elf cards that just happen to be next to eachother
This allows it to shoot down attackers before they have an opportunity to damage it, what an intimidating blocker
