【How-to】Does counterspell work on spell like abilities

In short I’d say 6-7 is ideal, so that you can draw into them when needed, and to answer other things. To help make the decision easier, look at counters that have other upside, (Cryptic Command, Mystic Confluence, etc.) so that the slot isn’t just a counterspell. All-in-one counters like Disallow are great as well.
