Another Beldum Question

Wether you evolve it tomorrow or not the rebalance will happen eventually. But if that's your best one evolving it tomorrow will give it the best steel move, no matter how good the move is.

Useless to ask this before you know what you catch tomorrow. But it's pretty good as far as level 30 Beldums go, I'd probably evolve it.

You'll probably enough beldum's tomorrow that are better than this.

Anything level 30 with 15 attack and at least 23 combined defense and stamina are unconditionally better. Any at level 25+ should really be considered too because Metagross is legitimately amazing. If not then sure, evolve this one - it's pretty good.

Going off of my larvitar CD, I found (without weather boost) 3 level 30 larvitar with 15 attack (and better overall IV's than the above), as well as wanting to evolve my highest IV (a level 8, 98%), a shiny, and picked to evolve two others in the mid-high level 20s with better IVs.

I think the OP thinks that the rebalance will change the iv’s. Their beldum currently has 15 defense which they believe will be reduced because of the rebalance.

I can tell you that that is 100% not the case. The rebalance affects the base stats underneath that the iv’s adjusts. Your beldum will still be 14/15/8 after the rebalance.
