OOO, OOO what are we sparring with? Kenbo sticks, staffs, or hands and feet? Actually it's just cool that your sense of humor actually comes across on the webpage. I don't think mine does that well. But back on topic, you are right, but in certain situations, some monsters can be harder to get rid of than others. I used to run Mage power in all my decks. It strenthened my monsters, but more often than not it became a Reaper reaper.

Unless they make a real invincible monster that's unaffected by all Magic, Trap and Monster Cards that can be Special Summoned very easily...(never happen)

That is true Half. Exodia Necross was the closest to that. But it fell prey to little man eating bugs, lol. Guardian Kayest also has some good built in immunities, but she has to have that equip card out first.

Great Dezard is actually very powerful if you kill 1 monster with it. If only it had a little more attack (if it be 2200 it be super excellent).

Actually, it's not "immune" to them though. It's only unable to be "destroyed" by Magic, Trap and Battle. Other things will still affect it though.
