These cards exclusively increases the attack of Beast-Type monsters.
Use Beast Rising by banishing 1 face-up Beast-Type or Beast-Warrior-Type monster from your field to increase the attack of Des Wombat. You can also use its banishing cost to dodge the attack of your opponent's monster.
After using Beast Rising, you can pump Des Wombat's attack even more by using Beast Rage. This card synergize well with Beast Rising since the attack increase depends on the number of banished Beast-Type monsters.
This card will bs used as much as Lifeforce Harmonizer, so basically not at all lol. No reason to tech something in for burn matchuos when you can tech in a card that isn't useless in every other matchup
I would say that there is some use of this card plus its not that bad 1600 atk is just okay. But the effect can really shut burn deck down. Potentially going to see this guy more on beast decks or maybe something like naturia pineapple deck
