I'll help you analyze the winrate of Izzet Elementals with different configurations of these cards. Let me start by searching for the cards and archetype.
Now let me query the database to find Izzet Elementals entries with at least 3 copies of Deceit and their performance against opponents with 4 copies of Badgermole Cub.
Izzet Elementals decks running at least 3 copies of Deceit have a 56.3% winrate against opponents playing 4 copies of Badgermole Cub in Standard. Across 16 recorded matches, these Izzet builds went 9-7-0, showing a modest but positive edge in the matchup.
The data is limited to 16 matches, so this should be interpreted as an early trend rather than a definitive result. Deceit's flexibility as a bounce or discard spell depending on mana spent appears to provide reasonable interaction against green-based strategies utilizing Badgermole Cub's mana acceleration.
