Forum:Is Ice Master Effected by Black Horn of Heaven?

Since Black Horn of Heaven only negates the inherent special summoning of effect monsters (and not the special summonings that cause a chain as it says in the card's ruling), does it effect Ice Master? Ice Master requires that you tribute 2 water monsters in order to special it therefore starting a chain. Can I assume that Black Horn of Heaven won't work on Ice Master then?

^_^ thank you.
