The twenty-first card is Number 41: Bagooska the Terribly Tired Tapir, probably filling in for the children with sugar-plums or a creature to go with the mouse. Bagooska is a rank 4 XYZ monster that takes two materials, and loses one each standby phase, so it will last for three turns before it runs out of materials and destroys itself. Its effect is different depending if its attacking or defending. If it is in attack mode then it can’t be destroyed or targeted by your opponents effects, and if it is in defense mode then everything else goes into defense mode and the things that were already there lose any activated effects. It’s moderately powerful at 2100 attack and 2000 defense, and if you use cards like Numbers Overlay Boost or XYZ Override then you can make it last on the field even longer. Its defense has gotten somewhat less effective because of link monsters and their inability to go into defense mode. Overall a great shield and a decent attacker, and thank you to Konami and Hill and Knowlton Strategies for giving us this Advent Calendar.
