If an Armor monster attacks an opponent's monster, until the end of the Damage Step, negate the effects of that monster while it is face-up on the field (but its effect can still be activated)
Personally, I've lost many duels due to time
Ghost Belle & Haunted Mansion or the always useful Ash Blossom & Joyous Spring can be good quick effect options to break your opponent strategy while cards like Summon Limit or the lv4 monster Vanity's Fiend can be provide more long term disruption to their chains
Finish the solo mode The solo mode in Master Duel is an excellent way of unlocking cards, getting extra gems, and learning more about different archetypes throughout the game
If you Tributed a Fusion Monster that mentions "Fallen of Albaz" as material to activate this card, you can Special Summon both monsters to your field instead, in Defense Position
Ok, I was sceptical about this at first as it seemed a lot of money for what looks like paper they are slim and unobtrusive so that was a big plus for me
