One of the best decks Ive had so far has been a straightforward Temur deck centered around blue and red
Card draw is another reward, often connected to paying mana, like with Shanna, Purifying Blade, Well of Lost Dreams, or Dawn of Hope
The fact that this card gets flying after growing makes it an excellent choice for a low-cost beater, and it has great synergy with cards that spread +1/+1 counters on others like Ouroboroid or white planeswalkers that make tokens and give +1/+1 counters to all creatures (Elspeth, Ajani)
This can be reduced even further by owning Legendary Creatures, which most decks do nowadays anyway
The Lord of the Rings: Tales of Middle-Earth Commander deck is perfect for both Tolkien fans and Commander players, blending iconic LOTR characters and themes with ready-to-play decks
This interaction will allow you to populate more than once each turn and go even wider
