Only one of each card forces you to play cards you might not otherwise because theyre too expensive or clunky
You can obtain the Burmy (1-Diamond rarity) card by opening Space-Time Smackdown: Dialga and Space-Time Smackdown: Palkia from Space-Time Smackdown set

You may find that the optimal numbers for your deck are completely different from this template
Its very much a control deck looking to answer opposing threats while bleeding away at opponents with the commander, Y'shtola, Night's Blessed
The deck starts by casting efficiently-costed creatures with strong secondary abilities including Sanguine Evangelist (1/1 tokens), Preacher of the Schism (1/1 tokens, card draw), Vanguard of the Rose (Indestructible), Echo of Dust (+1/+1, lifelink), and Bartolome (sacrifice outlet, +1/+1 counters)
