If the opponent activates a card that will destroy one or monsters on the field on resolution, then you can pay 1500 to activate My Body as a Shield. MBaaS will negate that destruction effect, so it will not resolve.
Simple scenarios involve Lightning Vortex, Mirror Force, Exiled Force, Dark Armed Dragon, Judgment Dragon, etc. As long as at least one monster will be destroyed on resolution, then MBaaS can be used to stop it.
'Shield and Sword', a Normal Spell Card, can do that.
'Chaos Shield' exists as 'Yellow Luster Shield', printed in Invasion of Chaos.
The two monsters depicted on the card are Gagagigo and Marauding Captain.
Yes. The card is card rotator from Yu-Gi-Oh 5'Ds.

No, it doesn't end the battle phase.
Yes, as long as the spell card is a Quickplay Spell, and the trap card is not a Counter Trap. So you cannot chain Monster Reborn to any trap. Nor can you chain Book of Moon to a Counter Trap, for example.
You are only allowed 11 cards as a maximum on a field, you have five monster card slots, five spell/trap slots, and a Field Spell Card slot.
