Not at all. If you realize that your meta demands it, you can even up the number and throw in some Urborg, Tomb of Yawgmoth.
The preferred choice should be Field of Ruin, because many decks play only 2 or 3 basics, but not this one, so at some point, it'll be an asymmetric effect in your favor.
I don't want to go with Thoughtseize as it drain my life... I already have other card that demands my to pay some of it.
The only out of standard card that demands hp is Bitterblossom, which is only a 2-of; it's a two color deck, then you can fetch for basics more than other decks and it's built around the drain life "mechanic", so Thoughtseize shouldn't be discarded (no pun intended).
