mtg cards like exploration exile the top card of your library Double Masters Borderless Exploration :

While I don't think it's one of the most competitive budget decks we've played in Amonkhet Standard, it's good enough to win some matches, even against tier decks

Obviously I have nitpicks with individual cards -- I've been yelling about Temple of the False God only being good in decks that reliably land ramp and it's especially bad in decks with lots of color pip requirements -- but these are just nitpicks

Y'shtola also synergizes well with common Black and White deck themes that focus on dealing small damage and healing outside of the player's combat

And if it dies, it goes into the command zone, so you cast it again

Best used with creatures with awesome ETB or attack triggers
