Hes allowed me to share a list similar to the one he won a League Challenge with recently (he changed it for the Lysandres Trump Card ban)
It's harder for Blue to deal with this stuff outright because the idea is that they can then counter them once bounced
In rarity they are the silver circle, meaning Common , the tall, white chevron means Uncommon , the bronze triangle means Rare, the silver square means Super Rare , and the gold pentagon means Legendary
Not only is Nashi a cheaper, sleeker Fallen Shinobi, but the ability to freecast from YOUR library opens the potential for control, which hampers other big Ninja payoffs
The First Sliver A deck with The First Sliver has a heavy restriction since it only lets slivers cascade, but slivers are the creature type to benefit from this mechanic
This card really gets strong, however, once you get a way to remove the counters/move them elsewhere
