The only issue with this deck is that it doesnt have a ton of cards that are still competitively viable today (with a few notable exceptions like Lefou Instigator and Shield of Virtue)
It is sometimes said that free counterspells are like the police of a format, keeping other decks in check and preventing absurd combo strategies from taking over
The fact that you can activate this card from your hand while you control no cards leads to a brutal strategy: All you need to do is skip your main phase 1, go right into the battle phase, then fire this off and banish your opponents entire field in one fell swoop
The set will mark the first block in the TCGs latest chapter- centered around Mega Evolutions
All you need is a card like Heartstone or Zirda, the Dawnwaker to reduce the cost of Sliver Queens effect, then cards like Earthcraft or Gemhide Sliver + a haste enabler, and you have access to infinite 1/1s
SIR Umbreon was a rare card to begin with, but that double scarcity, and being arguably one of the most beautiful modern cards released, is the reason why this card is currently worth just under $1000
