I thought so! I have hardly seen Magic Reflect monsters/summoners being in Gold III and below (I'm reluctant to go any higher with my collection currently), so even thought of a death summoner against magic sounded different.
But hey, now I know, thanks to you! This counter Water attack I highlighted in the blog works every time in the leagues I've been in, but I'm definitely buying our new Magic reflect friend as I move up in the league table!
