Forum:Lava Golem vs Kaiser Colosseum

I control 2 monsters and Kaiser Colosseum. My opponent controls 1 monster. Can my opponent summon Lava Golem to my side of the field? (asking because the tributing part makes me have less monsters than them) Also same situation but I have 3 monsters and my opponent is trying The Winged Dragon of Ra (Sphere Mode) Thechosenone124 (talk • contribs) 07:37, June 18, 2016 (UTC)
