Aprils Awesome Unbans The Commander unbans from April brought back some classics
Many frog commanders play in spaces that tie into having lands in your graveyard, whether youre sacrificing them to The Gitrog Monster or milling / surveilling them with Grolnok, the Omnivore or Glarb, Calamity's Augur
The most basic idea of a master set is every card in the numbered set, every Secret Rare, and every reverse holo (which reprint the non-Full Art cards with foil on the card's border and text area rather than on the background of the art)
Having access to a Sun Titan at such a low mana cost is wonderful, and you should play it in your white decks
It reduces the cost of your colorless Eldrazi spells by two generic mana, so all your big creatures are two mana cheaper, and when combined with other mana reducers like Shadow in the Warp, can help accelerate your creatures out several turns earlier than normal
